Description

Technical Field

[0001] The utility model relates to a mould, in particular to a front mould ejection mould with a sprue sleeve cooling. Background Art

[0002] For some products, the clamping force between the front mold and the back mold is not much different, which makes the product easy to stick to the front mold. In order to prevent the product from sticking to the front mold, the mold is designed with a front mold ejection mechanism, and the mold plate and gate sleeve are very long, resulting in a long injection molding cycle and reduced production efficiency. Utility Model Content

[0004] In order to achieve the above purpose, the measures taken by the utility model are:

[0005] A front mold ejection mold with gate sleeve cooling comprises an upper fixed plate, a support plate and a front mold plate, wherein the support plate is located between the upper fixed plate and the front mold plate, wherein guide columns pass through the upper fixed plate, the support plate and the front mold plate from top to bottom, wherein a panel groove is provided at the middle position of one side of the support plate close to the upper fixed plate, wherein an ejector panel and an ejector bottom plate are installed from inside to outside in the panel groove, wherein support columns pass through the ejector panel and the ejector bottom plate, wherein a reset rod passes through the front mold plate, the support plate, the ejector panel and the ejector bottom plate, wherein a spring is sleeved on a section of the reset rod extending into the upper fixed plate, wherein an ejector is provided on the ejector panel, and the ejector passes through the support plate and is pushed onto the front mold plate;

[0006] The upper fixed plate is provided with a cooling water channel, the quick connector of the cooling water channel is exposed from the side of the upper fixed plate, the cooling water channel in the upper fixed plate is connected to a sprue sleeve with cooling water, and the sprue sleeve passes through the ejector bottom plate, the ejector panel and the support plate to be connected to the cooling water channel in the front template;

[0007] A side positioning component is arranged on the outer side wall of the front template.

[0008] The utility model has the following beneficial effects: the structure is novel, the mold not only solves the risk of the product sticking to the front mold, but also ensures that the injection molding production cycle is not increased, thereby improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the external structure of the utility model.

[0010] Figure 2 It is a schematic diagram of the exploded structure of the utility model. DETAILED DESCRIPTION

[0011] A front mold ejection mold with gate sleeve cooling comprises an upper fixed plate 4, a support plate 5 and a front mold plate 6, wherein the support plate 5 is located between the upper fixed plate 4 and the front mold plate 6, and a guide column 9 passes through the upper fixed plate 4, the support plate 5 and the front mold plate 6 from top to bottom, a panel groove 501 is opened in the middle position of one side of the support plate 5 close to the upper fixed plate 4, an ejector panel 11 and an ejector bottom plate 10 are installed from the inside to the outside in the panel groove 501, a support column 2 passes through the ejector panel 11 and the ejector bottom plate 10, a reset rod 7 passes through the front mold plate 6, the support plate 5, the ejector panel 11 and the ejector bottom plate 10, a spring 3 is sleeved on a section of the reset rod 7 extending into the upper fixed plate 4, an ejector is provided on the ejector panel 11, and the ejector passes through the support plate 5 to be pushed onto the front mold plate 6.

[0012] The front mold is provided with an ejection mechanism, which includes a support plate 5, an ejector panel 11, an ejector bottom plate 10, a support column 2, a spring 3, and a reset rod 7, etc., which results in a very thick front mold plate 6 and a very long sprue sleeve 12. The ordinary cooling method cannot ensure uniform cooling of the sprue sleeve 12 in a very small space. In order to ensure the cooling of the sprue sleeve 12, the tool of the present application is made by 3D metal printing. When the sprue sleeve 12 has a diameter of 14 mm, a fan ring cross-section waterway is used inside, and a circular cross-section waterway is used outside.

[0013] like Figure 1 The figure shows the mold closing state. When the mold is opened, under the action of the spring 3, the ejector base plate 10 and the ejector panel 11 drive the ejector and the reset rod 7 to be ejected together; when the mold is closed, the male mold plate of the equipment hits the reset rod 7, compressing the spring 3 and returning the ejector to its original position.

[0014] A cooling water circuit is provided in the upper fixed plate 4, and a quick connector 1 of the cooling water circuit is exposed from the side of the upper fixed plate 4. The cooling water circuit in the upper fixed plate 4 is connected to a sprue sleeve 12 with cooling water. The sprue sleeve 12 passes through the ejector base plate 10, the ejector panel 11 and the support plate 5 and is connected to the cooling water circuit in the front template 6.

[0015] A side positioning assembly 8 is provided on the outer side wall of the front template 6 .
