Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds and is characterized by a layered product mold. Background Art

[0002] Injection molds are tools for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molds are also a processing method used in mass production of parts, mainly used in the industrial field. The injection mold process is to inject the heated and molten material into the mold cavity under high pressure, and after cooling and solidification, a molded product is obtained.

[0003] Due to the differences in structure between different layers of existing layered products, a side-opening middle mold structure is often required for easy demoulding, that is, the upper and lower molds must be opened before demoulding, and both sides must be opened. The demoulding of the product also requires the use of a demoulding drive mechanism to drive a demoulding rod to eject the product, and finally the ejected mold is removed manually or by equipment. This demoulding method cannot achieve self-demolding and material unloading, so it is not conducive to improving work efficiency. Utility Model Content

[0004] The utility model provides a layered product mold to solve the above technical problems.

[0005] The solution adopted by the utility model to achieve its technical effect is:

[0006] A layered product mold, comprising a base, a lower mold, a middle mold, an upper mold, a side demoulding mechanism and a top demoulding mechanism; the lower mold comprises a lower mold base and a lower mold core; the lower mold base is arranged on the base; oblique grooves are arranged on both sides of the top of the lower mold base; the lower mold core is arranged on the lower mold base; the middle mold is composed of two middle mold cores arranged on the lower mold base and the lower mold core for relative sliding; the upper mold comprises an upper mold base, a top seat, an upper mold core and an injection port; the upper mold base is pressed on the top of the lower mold base; the top seat is elastically arranged on the top of the upper mold base; the upper mold core is arranged at the bottom of the upper mold base, and the upper mold core is pressed on the top of the middle mold core; the lower mold core, the middle mold core and the upper mold core are surrounded to form a mold cavity; the injection port is arranged on the top of the upper mold base, and the injection port is connected to the mold cavity; the side demoulding mechanism comprises a movable seat and The cam is an angular channel formed between a pair of camshafts and a pair of camshafts, and the camshafts are connected to a pair of camshafts which are connected to the camshafts and are pressed against a pressure plate.

[0007] Preferably, a positioning groove is provided on the movable seat; a positioning block is provided at the bottom of the upper mold seat; the positioning block and the positioning groove are interlocked; and the top of the oblique guide rod is arranged in the positioning block.

[0008] Preferably, a positioning hole is provided on the outer side of the upper mold core; a positioning rod is provided on the inner side of the movable seat; and the positioning rod is slidably inserted into the positioning hole.

[0009] Preferably, a movable groove and an oblique slot are provided on the top of the upper mold core; a movable block is provided on the top of the oblique core-pulling slider; the movable block is movably arranged in the movable groove, and the spring is arranged between the movable block and the side wall of the movable groove; the bottom of the oblique slot is connected to the mold cavity; the oblique core-pulling slider and the clamping block are slidably inserted side by side in the oblique slot.

[0010] Preferably, a mounting groove is provided at the top of the upper mold core; the movable groove and the oblique slot are provided at the bottom of the mounting groove; a cover plate is provided on the mounting groove; and the cover plate is provided on the top of the movable block.

[0011] Preferably, an oblique guide groove is provided on the top of the movable block; an oblique guide block is provided on the bottom of the top seat; and the oblique guide block is slidably inserted in the oblique guide groove.

[0012] The beneficial effects of the utility model are as follows: when the mold is opened, the upper mold is separated from the lower mold, and the side demoulding mechanism automatically pushes the two middle mold cores of the middle mold to both sides, realizing simultaneous mold opening on three sides; when the top demoulding mechanism is working, the top seat is pressed down so that the clamping block clamps the oblique core-pulling slider, so that the bottom demoulding module of the oblique core-pulling slider is connected to the mold cavity, and after the product is formed, the top structure is hung on the outside of the demoulding module, so that after the mold is opened, the product follows the upper mold to separate from the lower mold, and then the pressure of the top seat is released, and the clamping block follows the release of the oblique core-pulling slider, causing the bottom of the oblique core-pulling slider to be obliquely withdrawn to the original position and separated from the product, thereby realizing self-demolding of the product. It can be seen that the demoulding efficiency of the utility model is high. BRIEF DESCRIPTION OF THE DRAWINGS
