Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a double-acting cup automatic gate cutting mold. Background Technology

[0002] In the field of precision casting mold technology, especially in mold systems used for wax pattern molding, the gate treatment method directly affects production efficiency and product quality. Traditional wax pattern molds mostly use an upper mold plate for wax injection, and a spring plate structure is used in conjunction with springs to cut off and remove the gate. Specifically, this method involves setting a layered structure in the upper mold plate and adding springs. When the mold opens, the spring force pushes the spring plate to move, thereby cutting off the gate from the wax runner. The existing technology has the following problems:

[0003] Because the existing spring plate wax removal method has poor spring stability and low reliability, it is prone to fatigue, especially after repeated molding, which causes the spring plate to fail to open in time, the wax channel to stick together, and wax removal to be difficult. Utility Model Content

[0004] This invention provides a double-acting cup automatic gate cutting mold to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] An automatic gate-cutting mold for a double-acting cup includes a lower mold mechanism and an upper mold plate. The upper mold plate is located directly above the lower mold mechanism. The lower mold mechanism includes a lower template. A pull-out template is slidably installed at the bottom of the lower template. A wax channel mold plate is fixedly installed at the bottom of the pull-out template. The top of the wax channel mold plate is in contact with the bottom of the lower template. Cylinders are fixedly installed on both sides of the lower template. Push plates are fixedly installed at the output ends of the two cylinders. The rear side of the push plate is fixedly connected to the front end of the pull-out template. A hand-operated valve is provided on the front side of the push plate. A wax channel groove is opened at the bottom of the wax channel mold plate. A wax channel body is engaged in the inner cavity of the wax channel groove. Several push rods penetrating into the inner cavity of the wax channel groove are evenly arranged on the top of the pull-out template.

[0007] A further improvement of the present invention is that: the bottom of the lower template is evenly provided with a number of wax cavities, and the inner cavity of each of the wax cavities is provided with a wax body; the left side of the lower template is provided with an air blowing hole, and the air blowing hole is respectively connected to the inner cavity of the wax cavities.

[0008] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0009] 1. This utility model provides a double-acting cup automatic gate cutting mold. By adopting a drawer-type structure and cylinder drive, it realizes automatic cutting and ejection of wax channel, avoiding the delay or failure problem caused by fatigue of traditional spring structure, greatly shortening the wax removal time, and improving the stability and rhythm of continuous production.

[0010] 2. This utility model provides a double-acting cup automatic gate cutting mold. By using a cylinder to push the pull template to precisely match the wax channel mold plate, it ensures that the gate is cleanly cut off and the wax channel is completely ejected. This solves the problem that the traditional spring structure is prone to wax channel adhesion and incomplete cutting, which affects product quality. It also reduces the scrap rate caused by improper operation or structural instability. Attached Figure Description

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] like Figure 1-3 As shown, this utility model provides an automatic gate cutting mold for double-acting cups, including a lower mold mechanism 1 and an upper mold plate 2. The upper mold plate 2 is located directly above the lower mold mechanism 1. The lower mold mechanism 1 includes a lower template 11. A pull-out template 12 is slidably installed at the bottom of the lower template 11. A wax channel mold plate 13 is fixedly installed at the bottom of the pull-out template 12. The top of the wax channel mold plate 13 is in contact with the bottom of the lower template 11. Cylinders 14 are fixedly installed on both sides of the lower template 11. Push plates 15 are fixedly installed at the output ends of the two cylinders 14. The rear side of the push plate 15 is fixedly connected to the front end of the pull-out template 12. A hand-operated valve 16 is provided on the front side of the push plate 15. A wax channel groove 17 is opened at the bottom of the wax channel mold plate 13. A wax channel body 19 is engaged in the inner cavity of the wax channel groove 17. Several push rods 18 that penetrate into the inner cavity of the wax channel groove 17 are evenly arranged on the top of the pull-out template 12.

[0017] After the mold is opened, the lower mold mechanism 1 separates from the upper mold plate 2. The upper mold plate 2 is raised to the highest position of the wax pressing machine. After the cylinder 14 is ventilated, the hand valve 16 is turned clockwise. The cylinder 14 uses the push plate 15 to move the pull template 12 and the wax channel mold plate 13 outward. By using the contact between the bottom of the wax channel mold plate 13 and the bottom of the lower template 11, the wax channel body 19 can be cut off, leaving the wax channel body 19 in the inner cavity of the wax channel groove 17. At the same time, the ejector rod 18 is activated to push upward, so that the wax channel body 19 is lifted. After the wax channel body 19 is pushed out by the ejector rod 18, it can be directly taken out. When resetting, the cylinder 14 is ventilated again, and the hand valve 16 is turned counterclockwise. The cylinder 14 can use the push plate 15 to drive the pull template 12 and the wax channel mold plate 13 to move inward. At the same time, the ejector rod 18 retracts back to its original position. After the hand valve 16 is reset, the wax pressing machine can lower the upper mold plate 2 to close the mold.

[0018] like Figure 1-3 As shown, the bottom of the lower template 11 is evenly provided with several wax cavities 111, and the inner cavity of each wax cavity 111 is provided with a wax body 112. The left side of the lower template 11 is provided with an air hole 113, which is connected to the inner cavity of each wax cavity 111.

[0019] Connect the air pump to the air blowing hole 113 and blow air to detach the wax body 112 from the wax body cavity 111, so that the wax body 112 can be quickly removed.

[0020] The working principle of this double-acting cup automatic gate cutting mold will be explained in detail below.

[0021] like Figure 1-3 As shown, after the mold is opened, the lower mold mechanism 1 separates from the upper mold plate 2. The upper mold plate 2 is raised to the highest position of the wax press. After the cylinder 14 is ventilated, the hand valve 16 is turned clockwise. The cylinder 14 uses the push plate 15 to move outward to pull out the template 12 and the wax channel mold plate 13. By using the contact between the bottom of the wax channel mold plate 13 and the bottom of the lower template 11, the wax channel body 19 can be cut off, leaving the wax channel body 19 in the inner cavity of the wax channel groove 17. At the same time, the ejector rod 18 is activated to push upward, causing the wax channel body 19 to be lifted. After the body 19 is pushed out by the ejector rod 18, it can be directly removed. Then, the air pump is connected to the air blowing hole 113 and air is blown out to detach the wax body 112 in several wax cavity 111. The wax body 112 can then be removed. Finally, the cylinder 14 is ventilated again, and the hand valve 16 is turned counterclockwise. The cylinder 14 can then drive the pull plate 12 and the wax channel mold plate 13 to move inward with the help of the push plate 15. At the same time, the ejector rod 18 retracts back to its original position. After the hand valve 16 is reset, the wax press can lower the upper mold plate 2 to close the mold.

[0022] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
