Description

Technical Field

[0001] This utility model relates to a moving mold support structure for a stacked mold. Background Technology

[0002] Plastic products are often produced using injection molds. There are many types of injection molds, among which stack molds are a type of injection mold that can increase production output.

[0003] Stacked molds generally consist of a moving mold, an intermediate mold, and a fixed mold arranged sequentially from left to right and cooperating with each other; during mold opening and closing, the moving mold can be translated in the left and right direction. Some stacked molds have an injection port at the top of the moving mold and an injection mechanism above the moving mold; the injection mechanism includes: an injection station fixed at the top of the moving mold, and a top-side nozzle that cooperates with the injection port; after the mold is closed, injection is performed through the top-side nozzle into the injection port at the top of the moving mold.

[0004] Because the injection port is located at the top of the moving mold, the top-side injection station needs to inject downwards, and the injection station is supported by the moving mold. Therefore, during injection molding, the injection mechanism will always exert downward pressure on the moving mold. The precise positioning of the moving mold will also be aggravated by the downward pressure of the injection mechanism, which will lead to inaccurate positioning of the moving mold and misalignment of the injection molded product. Summary of the Invention

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] The specific technical solution of this utility model is as follows:

[0022] like Figures 1 to 4As shown, this utility model provides a moving mold 11 support structure for a stacked mold 1. The stacked mold 1 includes a moving mold 11, an intermediate mold 12, and a fixed mold 13 arranged sequentially from left to right and cooperating with each other. When the mold is opened and closed, the moving mold 11 can be translated in the left and right direction. An injection port 110 is provided at the top of the moving mold 11, and an injection mechanism 2 is provided above the moving mold 11. The injection mechanism 2 includes: an injection table 21 fixed at the top of the moving mold 11, and a top-side injection nozzle 22 that cooperates with the injection port 110.

[0023] The support structure includes: a support beam 3 located directly below the moving mold 11, horizontally placed in the front-back direction and supporting the moving mold 11; a pair of guide rails 4 located below the stacking mold 1 and on the front and back sides of the stacking mold 1, both horizontally placed in the left-right direction; and a pair of linear bearings 5 ​​located on the pair of guide rails 4, which can be horizontally moved along the corresponding guide rails 4 and are fixedly connected to the front and back ends of the support beam 3 respectively.

[0024] The support beam 3 includes: a main body 31 located directly below the moving mold 11, horizontally placed in the front-back direction and fixedly connected to the bottom end of the moving mold 11 at its top end; and an outer extension 32 located on the front and rear sides of the moving mold 11, both horizontally placed in the front-back direction and integrally connected to the front and rear ends of the main body 31 respectively; the thickness of the main body 31 is greater than the thickness of the outer extension 32.

[0025] The top end of the main body 31 is fixed to the bottom end of the moving mold 11 by a first bolt. The main body 31 is provided with a first mounting hole 310 for mounting bolts (the first bolt is not shown in any of the figures).

[0026] The outer extension portion 32 corresponds to a pair of linear bearings 5 ​​one by one. The bottom end of the outer extension portion 32 is fixed to the top end of the corresponding linear bearing 5 by a second bolt. The outer extension portion 32 is provided with a second mounting hole 320 for mounting bolts (the second bolts are not shown in any of the figures).

[0027] The outer extension portion 32 is symmetrically arranged; the pair of linear bearings 5 ​​are symmetrically arranged; the pair of guide rails 4 are symmetrically arranged.

[0028] The working principle of the moving mold 11 support structure of the stacking mold 1 of this utility model includes:

[0029] The support beam 3 always supports the moving mold 11, and a pair of linear bearings 5 ​​can support the support beam 3 to move horizontally along a pair of guide rails 4, so that the support beam 3 can support the moving mold 11 to move horizontally in order to carry out mold opening and closing (the length of the pair of guide rails 4 is adapted to the moving distance of the moving mold 11 during mold opening and closing).

[0030] After the mold is closed, injection is performed through the top side nozzle 22 to the injection port 110 at the top of the moving mold 11;

[0031] Since the injection port 110 is located at the top of the moving mold 11, the top side injection station 21 needs to inject downwards, and the injection station 21 is supported by the moving mold 11. Therefore, during injection molding production, the injection mechanism 2 will always exert downward pressure on the moving mold 11.

[0032] Although the injection mechanism 2 will always exert downward pressure on the moving mold 11, the support beam 3 can always effectively support the moving mold, so that the moving mold 11 can withstand and balance the downward pressure from the injection mechanism 2. This can avoid or greatly reduce the wear of the moving mold 11 due to the constant downward pressure from the injection mechanism 2, thereby improving the production quality of the injection molded products.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
