Description

High-efficiency cutting device for casting head of glass mold

Technical Field

The invention belongs to the technical field of auxiliary equipment for manufacturing glass molds, and particularly relates to an efficient cutting device for a casting head of a glass mold.

Background

The function of the casting head is well known in the casting industry, in particular to add supplementary parts above and/or to the sides of the casting in order to avoid defects in the casting. In the casting mould, the cavity of the casting head is a container for storing liquid metal, the functions are manifold, and the forms, sizes and opening positions of the casting heads with different functions are different, so that the design of the casting head needs to take the characteristics of castings with different products into consideration. In patent documents, not limited to the following examples, technical information related to the glass mold casting head is mentioned to various degrees, such as CN102672113A (method of casting copper alloy die of glass mold from resin sand single box), CN102430700A (method of casting copper alloy bottom mold of glass mold from resin sand single box), CN102828103B (alloy gray cast iron glass mold and preparation method thereof), and CN111334684A (solid-liquid state high toughness high thermal conductivity copper alloy glass mold and preparation method thereof), and so on.

For glass molds of copper alloys, such as dies, which are usually obtained by casting, casting heads are left in the final cast part to ensure the quality of the cast part, as described above, and the casting heads need to be removed before the glass mold is initially machined, otherwise subsequent initial machining processes cannot be performed.

In the prior art, a casting head on a copper alloy glass mold or a similar glass mold is usually removed by a worker in an operation mode of manually clamping and manually cutting off (sawing off), and since the end surface of the casting head after the manual cutting off, namely sawing off, is very rough, a milling machine is required to mill and flatten the casting head after the cutting off. One of the defects of the operation modes is that the operation intensity of workers is high; the second disadvantage is that the processing efficiency is low and cannot be adapted to the requirement of industrial high-efficiency production; the third disadvantage is that the manual processing requires a large amount of workers, which is not favorable for saving precious labor resources.

Due to the special shape of the glass, there is no technical teaching in the prior art patent and non-patent literature that can compensate for the above-mentioned deficiencies, and for this reason the applicant has made an advantageous design, and the technical solutions described below have been made in this context.

Because the operator is in the clamping work of the clamping mechanism II 6 for the glass die to be cut of the second casting head in the time for cutting the glass die to be cut 9 of the casting head on the clamping mechanism I5 for the glass die to be cut of the first casting head, when the glass mold to be cut of the casting head on the first glass mold to be cut clamping mechanism I5 finishes the cutting of the casting head and the clamping platform 51 is retreated to the front, namely to the position state of the figure 1, the operator operates the operating handle 1321 in the other direction to displace the second to-be-cut-off-head glass mold clamping mechanism ii 6 in the direction of the circular saw 27 (i.e., backward) with the to-be-cut-off-head glass mold 9 having a to-be-cut-off head, which has been clamped, therefore, the first dead head glass mold to be cut clamping mechanism I5 and the second dead head glass mold to be cut clamping mechanism II 6 are displaced alternately.

In the process of the aforementioned alternate displacement of the first to-be-cut glass mold clamping mechanism i 5 and the second to-be-cut glass mold clamping mechanism ii 6, according to the applicant's above, the circular saw driving motor support base sliding engagement frame 44 of the structural system of the circular saw up-down displacement mechanism 4 is displaced by the circular saw left-right displacement mechanism 3 in a left-right alternating manner together with the entire circular saw driving mechanism 2, and when the to-be-cut glass mold 9 of the riser on the first to-be-cut glass mold clamping mechanism i 5 is cut off, the circular saw driving mechanism 2 is moved down under the action of the circular saw driving motor support base up-down displacement driving screw 43 to cut off the riser, or vice versa.
