Description

A mold that can realize automatic separation of edging gate of skylight glass

technical field

The utility model relates to an injection mould, in particular to a mould which can realize automatic separation of the edging gate of skylight glass.

Background technique

In the glass edging mold, due to the isolation effect of the glass, the separation of the gate is difficult to be separated by pulling the lower mold. In addition, because the adhesive is used to bond the soft glue and the glass, it is easy to open the glue in the hot state, so it is difficult to use the hidden gate of the conventional mold to cut the gate. In particular, for the skylight glass edging mold, since the gate must be set on the glass surface, it can only rely on manual processing after the mold is opened, which consumes a lot of manual labor, and the shape of the gate cut off is due to the individual difference of the operator (the degree of the number of operations). factors) will vary.

Therefore, there is a need for a method or apparatus that can solve the above-mentioned problems.

Utility model content

In order to solve the above-mentioned deficiencies in the prior art, the utility model proposes a mold that can realize automatic separation of the edging gate of the skylight glass without manual intervention, can greatly improve the work efficiency, and ensure uniform quality.

The technical solution of the present utility model is: a mold that can realize automatic separation of the edging gate of skylight glass, comprising an upper mold 1 and a lower mold, and is characterized in that: the top of the upper mold 1 is provided with a flow channel block 2, A gate inner sleeve 3 is arranged below the runner block 2, and a conical gate runner 4 is opened inside the gate inner sleeve 3. The gate inner sleeve 3 is connected by a disc part located at the top and The cylindrical portion at the bottom of the disc portion is composed of two parts, a gate jacket 5 is attached to the cylindrical portion, and a sinker 6 is arranged on the top of the gate jacket 5, and a sinker 6 is arranged in the sinker The spring 7 outside the cylinder part, the top end of the spring 7 is in contact with the bottom end face of the disc part of the gate inner sleeve 3,

The upper die 1 is also slidably connected with a product pressing block 8, the top of the product pressing block 8 is fixedly connected with the bottom end face of the sink 6, and the bottom of the upper die 1 is provided with a plurality of broaches 9, The bottom end of the broach 9 is the blade portion 10,

The glass part 11 of the product is arranged in the cavity formed after the upper mold 1 and the lower mold are closed, and the plastic part 12 of the product can be formed in the cavity other than the glass part 11 . The bottom end corresponds to the part of the plastic part 12 to be retained, and the blade part 10 corresponds to the connection between the part of the plastic part 12 to be retained and the waste part.

Compared with the prior art, the utility model has the following advantages:

This structural form can realize the automatic separation of the edging gate of the skylight glass, and it has a simple structure, ingenious design and reasonable layout. A special structure is created, and its interior is equipped with a broach that matches the number and position of the product gate, so that the broach automatically cuts off the gate during the mold opening process, so as to realize the part and waste that the product needs to keep. The complete separation between the parts means that there is no need for manual cutting again, and the gate is automatically cut off during the mold opening process; after the mold is opened, the fertilizer in the runner will automatically drop from the runner, and the whole process does not No manual intervention is required, while saving manual labor, the production efficiency of such products can be greatly improved, the time cost and economic cost can be reduced, and the quality of the product incision can be guaranteed. At the same time, its manufacturing process is simple and the manufacturing cost is low, so it can be said that it has many advantages, and is especially suitable for popularization and application in this field, and its market prospect is very broad.

Detailed ways

The specific embodiments of the present invention will be described below with reference to the accompanying drawings. As shown in Figure 1 to Figure 5: a mold that can realize automatic separation of the edging gate of skylight glass, including an upper mold 1 and a lower mold, the top of the upper mold 1 is provided with a flow channel block 2, the flow channel A gate inner sleeve 3 is arranged below the block 2, and a conical gate runner 4 is opened inside the gate inner sleeve 3. The gate inner sleeve 3 consists of a disc portion located at the top and a connection to the disc portion. The cylindrical part at the bottom end is composed of two parts, a gate jacket 5 is attached to the outer shell of the cylinder part, and a sinker 6 is arranged on the top of the gate jacket 5, and a sinker 6 sleeved outside the cylinder is arranged in the sinker. A spring 7, the top of the spring 7 is in contact with the bottom end face of the disc portion of the gate inner sleeve 3,

The upper die 1 is also slidably connected with a product pressing block 8, the top of the product pressing block 8 is fixedly connected with the bottom end face of the sink 6, and the bottom of the upper die 1 is provided with a plurality of broaches 9, The bottom end of the broach 9 is the blade portion 10,

The glass part 11 of the product is arranged in the cavity formed after the upper mold 1 and the lower mold are closed, and the plastic part 12 of the product can be formed in the cavity other than the glass part 11 . The bottom end corresponds to the part of the plastic part 12 to be retained, and the blade part 10 corresponds to the connection between the part of the plastic part 12 to be retained and the waste part.

The working process of the mold that can realize the automatic separation of the edging gate of the skylight glass according to the embodiment of the present invention is as follows: first, the glass part 11 of the product is placed in the lower mold, and after the mold is closed, the glass part is located in the joint formed by the upper mold 1 and the lower mold. In the cavity, the molten material is poured into the gate runner 4 through the gate set on the runner block 2, and the material finally enters the cavity, and is wrapped around the outer edge of the glass part 11 after cooling and forming ( At this time, the spring 7 is in a compressed state);

After the material is formed, the mold is opened, and the upper mold 1 moves upward. During the upward movement, the broach 9 at the bottom also moves upward, and the blade 10 of the broach 9 automatically retains the part in the plastic part 12 during the movement. The cutting action is performed between the waste part and the waste part, and the connection between the two is cut off; in the above process, as the distance between the upper die 1 and the lower die gradually increases, the spring 7 stretches and pushes the gate jacket 5 and the lower die. The product pressing block 8 is stationary relative to the lower mold. At this time, the product pressing block 8 is pressed on the plastic part 12 to prevent pulling at the gate during the cutting process, causing the product to be stretched or even glued. The waste part in the mouth runner 4 will be completely separated from the part that needs to be retained in the product;

The upper mold continues to move upward. When the spring 7 is in a fully extended state, the product pressing block 8 will also be separated from the surface of the product. At this time, due to the complete separation of the gate and the inner sleeve of the gate, the self-weight of the gate and the gap between the gate and the glass Under the action of the vacuum effect, the waste part in the gate runner 4 automatically falls off and falls out of the gate runner 4. The operator only needs to take out the formed product from the cavity of the lower mold, then Proceed to the next pouring operation.
