Background technique

In today's world, the application of plastic materials and their products has involved all walks of life, all aspects, and even every family. More and more business people are involved in the production and sales of plastic products.

At present, in the thermosetting injection molding industry, it is usually necessary to separate the product and the material of the sprue, and the runner can only be sheared by the post-engineering fixture. In this case, the production efficiency will be reduced, and the labor cost will also be increased. Therefore, it is necessary to provide a gate device that can automatically cut the gate without increasing the labor cost.

Utility model content

In order to solve the above technical problems, the utility model proposes a device that can automatically cut off the sprue in the production process. The plate B moves forward to cut the gate straight, realizes the gate cut off, ejects the discharge handle, and takes out the product.

The utility model adopts the following technical solutions:

A thermosetting mold sprue automatic cutting device, the device comprises a push plate bottom plate B, a mold push plate B, a push plate bottom plate A, a mold push plate A, a cutter, an injection molding machine push rod, a sprue, and a reset rod A , a moving template, a mold moving mold base plate, a reset rod B, the reset rod A is connected with the mold push plate A, the mold push plate A is connected with the moving template, and the mold push plate A is equipped with an ejector rod, so The bottom plate A of the push plate is connected with the mold push plate A, and the mold push plate B is equipped with a reset rod B and a cutter, and the cutter runs through the push plate bottom plate A and the mold push plate A until the gate, and the The plate bottom B is connected with the mold push plate B, the push plate bottom B is connected with the mold movable mold bottom plate, and the injection molding machine push rod passes through the mold movable mold bottom plate and is pushed to the push plate bottom plate B.

Further, the top end of the cutter and the product parting surface are adjusted to the same plane.

Further, the thickness value of the sprue is the distance between the bottom plate A of the push plate and the push plate B of the mold.

The advantages and effects of the utility model are:

The device of the utility model realizes the automatic cutting of the gate by the cutter by reducing the distance between the push plates. This device needs to automatically cut off the sprue before the mold is opened, and then open the mold to eject the material and take out the product. Simple structure, convenient and practical. The device of the utility model optimizes the work flow, reduces the labor cost and improves the work efficiency.

Parts in the figure: 1 is the push plate bottom plate B, 2 is the mold push plate B, 3 is the push plate bottom plate A, 4 is the mold push plate A, 5 is the cutter, 6 is the injection molding machine push rod, 7 is the sprue, 8 is the reset rod A, 9 is the movable platen, 10 is the bottom plate of the mold movable mold, and 11 is the reset rod B.

Detailed ways

The present utility model will be further explained below in conjunction with the accompanying drawings and embodiments.

A sprue automatic cutting device includes: mold push plate A 4, mold push plate B 2, push plate bottom plate A 3, push plate bottom plate B 1, cutter 5, reset rod A 8, reset rod B 11, mold moving Die bottom plate 10, movable platen 9.

The reset rod A8 is installed on the diagonal part of the mold push plate A4, and the mold push plate A4 is connected with the movable template 9. In the figure, between the mold push plate A4 and the movable template 9 is the space for moving the push plate. The push plate A4 is equipped with an ejector rod, the push plate bottom plate A3 is assembled under the mold push plate A4, and the mold push plate B2 is equipped with a reset rod B11 and a cutter 5, and the cutter 5 penetrates the push plate bottom plate. A3 and the mold push plate A4 up to the sprue 7, the reset rod B11 is installed on the mold push plate A2 and penetrates the push plate bottom plate A3 and the mold push plate A4, the upper part and the movable platen leave a movable space. The product parting surface is adjusted to the same plane. The thickness of the sprue 7 is the distance between the push plate bottom plate A3 and the mold push plate B2. The push plate bottom plate B1 is installed at the lower part of the mold push plate B2, and the mold movable mold bottom plate 10 is assembled under the push plate bottom plate B1. The injection molding machine push rod 6 passes through the mold movable mold bottom plate 10 to push the push plate bottom plate B1.

Example 1

Install the mold push plate A 4 and the reset rod A 8 on the movable platen 9 first, and then install the ejector rod on the mold push plate A 4. Then install the push plate bottom plate A 3 and the mold push plate B 2, tighten the screws on the push plate bottom plate A 3, and fix the push plate bottom plate A 3 and the mold push plate A 4 together. Install the reset rod B 11 and the cutter 5 on the die push plate B 2. The top of the cutter 5 and the parting surface of the product are adjusted to the same plane. Reinstall the push plate base B1. Finally, the movable mold base plate 10 is installed. The mold push plate B 2 and the push plate bottom plate B1 are fixed on the movable mold bottom plate 10 . The thickness value of the sprue 7 is set as the distance between the push plate bottom plate A 3 and the mold push plate B 2 . The purpose is that before the mold is opened, the injection molding machine push rod 6 pushes the mold push plate B 2 and the push plate bottom plate B 1 forward, and the cutter 5 moves forward with the mold push plate B 2 and starts to cut the gate 7 straight. When the mold push plate B 2 is in direct contact with the push plate bottom plate A 3, the sprue 7 is completely cut off. After the gate is cut off, the mold is opened, and at the same time, the push plate and the ejector rod continue to move forward, the ejection handle is ejected, and the product is taken out.
