Description

Combined mold for making box shell

technical field

The invention relates to a mold, in particular to a combined mold for making a box shell.

Background technique

In recent years, due to the booming economy and convenient transportation, the opportunities for traveling abroad have greatly increased. Therefore, suitcase manufacturers have continuously developed various suitcases to meet the needs of consumers.

Most of the previous suitcase shells are made of plastic material, and the plastic material can be made into a hollow shell by blow molding or blister molding.

But in recent years, due to the advancement of technology and the user's demand for the strength of the suitcase, the material for making the suitcase has also been changed from pure plastic material to fiber-reinforced plastic laminate. Because the fiber layer in the fiber-reinforced plastic laminate has high strength and is not easy to shape, it is not suitable for blow molding or blister molding, and must be made by molding.

Existing a kind of molding equipment (US 8663531B2 patent case) that is used to manufacture box shell, comprises a female mold and a male mold with a mold cavity, when a fiber reinforced plastic laminate is arranged on this female mold top surface, and make The female mold is relatively close to the male mold, and when the reinforced plastic laminate is heated and softened, the fiber reinforced plastic laminate can be molded.

Although the above-mentioned molding equipment can be used to manufacture the case shell, because the general luggage has a front case shell and a rear case shell, the front case shell and the rear case shell are not only different in thickness, but also may have different texture designs on the surface. The top of the rear case must be equipped with a tie rod seat, so the shape of the rear case will be different from that of the front case. Furthermore, there are many sizes of suitcases and various pattern designs. As a result, manufacturers must manufacture a large number and variety of molds in order to manufacture various styles and sizes of front case shells and rear case shells. Also stay high.

The male base 40 has an upper end surface 41, a mold base 42 protruding downward from the upper end surface 41 and capable of being placed inside the mold cavity 12, and an upper concave hole 43 disposed on the mold base 42. The mold base 42 has a bottom side 421 opposite to the upper end surface 41 and a mold side 422 extending from the bottom side 421 towards the upper end surface 41, and the upper concave hole 43 can extend from the bottom side 421 to the mold side 422 Opposite sides.

One of the male pattern modules 50, 50' is fixed in the upper concave hole 43, and has a male pattern surface 51, 51' opposite to the female pattern surface 21, 21' and several The male pattern surface 51, 51' is opposite to the male pattern portion 52, 52' of the female pattern portion 22, 22', the male pattern portion 52, 52' is in the same shape as the female pattern portion 22, 22' Concave and convex complement each other. And the male pattern module 50' also has a sunken portion 53' corresponding to the protrusion 23'.

The male thickened seat 60 is generally in the shape of a rectangular plate, and is detachably fixed on the upper surface 41 of the male base 40 .

The heating and cooling unit 300 includes a first channel 71 provided on the female base 10 , a second channel 72 provided on the female base 30 , and a third channel 73 provided on the male base 40 And a fourth flow channel 74 arranged on the male thickening seat 60, the first flow channel 71, the second flow channel 72, the third flow channel 73 and the fourth flow channel 74 can respectively introduce and export heating and cooling fluids. The first runner 71 is arranged on the bottom side of the mold bottom 121 of the female base 10 , the second runner 72 is arranged around the inside of the female thickened seat 30 , and the third runner 73 is arranged on the male base 40 Between the bottom surface 421 and the upper end surface 41 , the fourth channel 74 is disposed inside the male thickened seat 60 .

As shown in Figures 1 and 3, before making the front box case 410, first select the female pattern module 20 with the predetermined female pattern part 22, and lock it to the female pattern module 100 of the female pattern unit 100 with several screws. In the concave hole 13 of the base 10 , and make the mold bottom surface 121 and the female pattern mold surface 21 flat. Next, as shown in FIG. 2 and FIG. 3 , select the male pattern module 50 with the predetermined male pattern portion 52 , and lock it in the upper concave hole 43 of the male base 40 of the male mold unit 200 with several screws. , and make the bottom side 421 and the male tread surface 51 flat. The male mold unit 200 is disposed above the female mold unit 100 .

In the state that the male mold unit 200 is mold-opened relative to the female mold unit 100, a fiber reinforced plastic laminate 1 (such as a carbon fiber reinforced plastic laminate or a glass fiber reinforced plastic laminate) that is heated in advance and has plasticity laminate) is placed on the top surface 11 of the female mold unit 100, and a fluid with a heating effect and a predetermined temperature is introduced into the first flow channel 71 of the female base 10 and the third flow channel of the male base 40 Flow 73 can make the female mold unit 100 and the male mold unit 200 achieve the purpose of preheating.

When the male mold unit 200 is operated to close the mold towards the female mold unit 100 (see Figure 4), the fiber-reinforced plastic laminate 1 will be molded, and after a predetermined time, it will have a cooling effect. And the fluid with lower temperature is introduced into the first flow channel 71 and the third flow channel 73, so that the female mold unit 100 and the male mold unit 200 can be cooled, and the shaped front box shell 410 can be shaped Purpose.

When the male mold unit 200 is in an open state relative to the female mold unit 100 , the front case shell 410 can be manufactured.

As shown in Fig. 1 and Fig. 5, when the rear case 420 is to be manufactured, since the rear case 420 has a larger thickness than the front case 410, the predetermined female pattern portion 22' is selected first. The female pattern module 20' is locked in the concave hole 13 of the female base 10 of the female mold unit 100 with several screws, and then the female thickening seat 30 is locked on the female base with several screws The top surface 11 of the seat 10 can utilize the inner hole 31 to increase the depth of the mold cavity 12 .

Continue, as shown in FIG. 2 and FIG. 5 , select the male pattern module 50 ′ with the predetermined male pattern portion 52 ′, and lock it to the upper concave hole of the male base 40 of the male mold unit 200 with several screws 43, the male thickened seat 60 is locked on the upper end surface 41 of the male base 40 with several screws, so that the male thickened seat 60 can be used to increase the overall height of the male mold unit 200.

As shown in Figure 6, when the male mold unit 200 and the female mold unit 100 are operated to close and open the mold, the fiber reinforced plastic laminate 1 will be molded to form the rear case 420, because The manufacturing method of the rear box shell 420 is the same as that of the front box shell 410, so it will not be further described.

Therefore, utilize the cooperation of the whole component of the combined mold of making box case in the present invention, and utilize single female base 10 to cooperate with different female pattern modules 20, 20', female thickening seat 30, and utilize single male base 40 and different male pattern modules 50, 50' and male thickened seat 60 can be used to manufacture front case shells 410 or rear case shells 420 with different textures and shapes, and it is not necessary to change the female base 10 and the male base 40, only need to change the female thickening seat 30 and the male thickening seat 60 of different thicknesses, the female pattern modules 20, 20' and the male pattern modules 50, 50' of different textures , can produce more styles of case shells, thereby reducing mold types and reducing mold manufacturing costs, can indeed solve the technical problems caused by existing case shell molds, and can greatly reduce the manufacturing cost of case shells.

To sum up, the combined mold for making the box shell of the present invention has a simple overall structure and is easy to assemble and disassemble components, and can indeed achieve the purpose of the present invention.
