Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection mold which is convenient for taking out materials. Background Art

[0002] Injection molds are important process equipment for producing various industrial products. With the rapid development of the plastics industry, injection molds are widely used in various industries, bringing various conveniences. After the injection molding is completed, a robotic arm is needed to remove the injection molded parts, that is, stripping.

[0003] After the injection mold is formed, when the finished product needs to be taken out, the mold formed inside the mold cavity is often manually taken out, which is prone to burns caused by accidentally touching the mold body; and because the thickness required for injection molding is different, the mold needs to be frequently replaced to meet the thickness requirements, making the whole process more cumbersome and reducing the demoulding efficiency. Therefore, those skilled in the art provide an injection mold that is convenient for taking out materials to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an injection mold that is convenient for material removal. It can not only change the thickness of the mold cavity, but also quickly eject the molded mold after processing and injection molding, which is convenient for workers to remove materials and reduce scalding accidents.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An injection mold for convenient material removal, comprising a lower mold base, side plates are fixedly arranged on both sides of the upper end surface of the lower mold base, and a top plate is fixedly arranged on the upper end surface of the side plate, a hydraulic push rod is fixedly arranged at the midpoint of the upper end surface of the top plate, a connecting plate is fixedly arranged at the lower end of the hydraulic push rod, and connecting blocks are fixedly arranged on both sides of the lower end surface of the connecting plate, an upper mold base is fixedly arranged on the lower end surfaces of the two connecting blocks, an inner plate is embedded at the midpoint of the upper end surface of the lower mold base, linkage rods are fixedly arranged on both sides of the lower end surface of the inner plate, and linkage plates are fixedly arranged at the lower ends of the two linkage rods;

[0007] A telescopic mechanism is provided on one side of the lower end surface of the lower die seat, and the telescopic mechanism includes an outer seat and an inner seat. A worm gear is embedded in one side of the interior of the lower die seat, and a threaded column is fixedly sleeved on the lower end of the worm gear. A worm is rotatably embedded on one side of the interior of the lower die seat close to the worm gear. An auxiliary mechanism is provided at the front and rear ends of the side of the lower end surface of the lower die seat away from the telescopic mechanism, and the auxiliary mechanism includes an auxiliary outer sleeve seat and an auxiliary inner sleeve seat.

[0008] Through the above technical solution, an upper mold base with a liftable upper end and a lower mold base with a fixed lower end are set. When injection molding is performed, the upper and lower mold bases are merged, and injection molding is performed through the injection hole at the top. Since the lower mold base is provided with an inner plate that can be adjusted as needed, the height of the inner plate changes so that the distance between the mold groove of the lower mold base and the top cover groove of the upper mold base changes, so that workpieces of various thicknesses can be injection molded, which can meet the use of workpieces of various thicknesses without changing the mold, and has stronger functionality and higher practicality.

[0009] Furthermore, a sliding groove is provided at the midpoint of one side opposite to the other of the two side plates, and the two ends of the upper die seat are respectively slidably embedded in the two sliding grooves;

[0010] Through the above technical solution, the moving direction of the upper die seat is restricted, the structure is simple, and the use is convenient.

[0011] Furthermore, a threaded block is threadedly sleeved on the outer side of the threaded column, one end of the linkage plate is fixedly connected to the threaded block and the other end is fixedly connected to the outer wall of the outer seat;

[0012] Through the above technical solution, the moving direction of the threaded block is guaranteed to be determined, thereby preventing the threaded block from rotating and becoming unable to move.

[0013] Furthermore, the outer seat is slidably sleeved on the upper end surface of the inner seat, and a No. 1 base is fixedly provided on the lower end surface of the inner seat;

[0014] Through the above technical solution, smoothness of height adjustment is guaranteed.

[0015] Furthermore, the auxiliary outer sleeve seat is fixedly sleeved on the outer side of the auxiliary inner sleeve seat, a No. 2 base is fixedly arranged on the lower end surface of the auxiliary inner sleeve seat, and the lower end of the threaded column is rotatably arranged in the No. 2 base;

[0016] Through the above technical solution, the auxiliary outer sleeve seat is fixedly sleeved on the outer side of the auxiliary inner sleeve seat to complete the fixed support effect of the entire lower mold seat.

[0017] Furthermore, one end of the worm penetrates through one side of the outer wall of the lower die base and is fixedly provided with a turntable, and the worm is meshingly connected with the worm wheel;

[0018] Through the above technical solution, when the worm rotates, it can drive the worm wheel to rotate, and at this time, the threaded column at the lower end of the worm wheel rotates synchronously.

[0019] Furthermore, a mold cavity is provided at the midpoint of the upper end surface of the lower mold base and the midpoint of the lower end surface of the upper mold base, and the inner plate is embedded in the mold cavity of the lower mold base and the outer wall of the inner plate is in contact with the inner wall of the mold cavity;

[0020] Through the above technical solution, the position of the inner plate can be changed as needed to change the thickness of the mold cavity.

[0021] The utility model has the following beneficial effects:

[0022] 1. The utility model proposes an injection mold that is convenient for taking out materials. By setting an upper mold base and a lower mold base separated from each other, when it is necessary to produce injection molded parts, the two are combined to inject liquid from the injection hole at the top. After cooling, the injection molded parts can be taken out by directly pushing up the inner rod. There is no need to manually touch the mold base to take out the finished product, which avoids scalding accidents. The utility model is simple to operate, which solves the problem that it is inconvenient for workers to take out the finished product after the injection molding is completed in most current injection molds.

[0023] 2. The utility model proposes an injection mold which is convenient for material removal. By adjusting the height of the inner plate embedded in the lower mold base at the lower end, when injection molding of molds of different thicknesses is required, the worm can be rotated to drive the worm wheel and the threaded column at the lower end of the worm wheel to rotate. At this time, since the threaded block is threadedly sleeved on the outside of the threaded column and the threaded block is connected to the linkage plate, the linkage rod and the inner plate, the inner plate can be synchronously lifted and lowered under the linkage action of the threaded block, causing the distance between the mold cavity of the lower mold base and the upper mold base to change, so that workpieces of different thicknesses can be injection molded, which can meet the use of buckle covers of various thicknesses. This can be completed without changing the mold, and the functionality is stronger and the practicality is higher. BRIEF DESCRIPTION OF THE DRAWINGS
