Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a soft rubber mold capable of controlling the thickness and rubber position of a product. Background Art

[0002] Among the soft rubber products currently on the market, Figure 1 Take the product in the example as an example, in order to achieve Figure 1 The effect of the ultra-thin thickness of the ring at the middle and thin glue position 100 is usually achieved by relying on secondary CNC processing or hot melt process after the product is injection molded. It has the disadvantages of low efficiency and high cost and cannot meet production needs.

[0003] Therefore, the existing technology has defects and needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a soft glue mold capable of controlling the thickness of the glue position of the product.

[0005] The technical solution of the present invention is as follows: The present invention provides a soft glue mold that can control the thickness of the product glue position, including: a mold body, the mold body includes a mold base, and a mold core and an inner mold top structure arranged on the mold base, the inner mold top structure includes a driving component and an inner mold top movable insert connected to the driving component, the inner mold top movable insert is used to move and extrude the thin glue position of the product under the drive of the driving component during injection molding.

[0006] Furthermore, the in-mold top structure also includes a reset structure, which is connected to the in-mold top movable insert and is used to drive the in-mold top movable insert to reset.

[0007] Optionally, the number of the in-mold top structures is greater than 1.

[0008] Furthermore, the driving component is a micro oil cylinder, and the mold body includes an oil pressure interface connected to the micro oil cylinder.

[0009] Furthermore, the oil pressure interface is connected to the high-speed oil pressure machine through an explosion-proof oil pipe.

[0010] By adopting the above scheme, the beneficial effect of the utility model is that: by setting the top structure in the mold, the thin glue position of the product can be moved and squeezed during injection molding, so that the thin glue position structure of the product can be formed during injection molding without the need for subsequent processing, thereby improving the production efficiency of the product and reducing the production cost.

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please refer to Figure 2 and Figure 3 In this embodiment, the utility model provides a soft glue mold that can control the thickness of the product glue position, including: a mold body 1, the mold body 1 includes a mold base 2, and a mold core 3 and an inner top structure arranged on the mold base 2, the inner top structure includes a driving member 4 and an inner top movable insert 6 connected to the driving member 4, the inner top movable insert 6 corresponds to the thin glue position setting of the injected product, and the inner top movable insert 6 is used to move and extrude the thin glue position of the product under the drive of the driving member 4 during injection, and extrude the material at this position to obtain a corresponding thin glue position structure.

[0016] Furthermore, the in-mold top structure also includes a reset structure 5, which is connected to the in-mold top movable insert 6. The reset structure 5 includes a reset spring for driving the in-mold top movable insert 6 to reset.

[0017] Furthermore, the driving component 4 is a micro-cylinder, and the mold body 1 includes a hydraulic interface 7 connected to the micro-cylinder for realizing the input and output of hydraulic power. The hydraulic interface 7 is connected to the high-speed hydraulic press through an explosion-proof oil pipe to realize the transmission of hydraulic power from the high-speed hydraulic press to the micro-cylinder.

[0018] It is worth noting that in this solution, the number of the in-mold top structures can be greater than one group. In actual production, the corresponding number of in-mold top structures can be selected according to the structure of the product and the mold.

[0019] To sum up, the beneficial effects of this solution are: by setting up an in-mold top structure, the thin glue position of the product can be moved and squeezed during injection molding, so that the thin glue position structure of the product can be formed during injection molding without the need for subsequent processing, thereby improving the production efficiency of the product and reducing production costs.

[0020] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
