Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold for plastic toys that is easy to demold. Background Technology

[0002] Plastic toys are a type of toy that is more suitable for toddlers than toys made of other materials. The raw material of plastic toys is a high-molecular synthetic resin as the main component, mixed with various auxiliary materials or additives. Under specific temperature and pressure, it has plasticity and fluidity, can be molded into a certain shape, and can maintain its shape under certain conditions.

[0003] A search revealed that patent application CN212764517U discloses a mold for plastic toys that facilitates demolding. The mold includes a lower mold base, an upper mold base, two sets of cooling components, and a pushing component. A guide frame is installed on one side of the upper surface of the lower mold base, and the upper mold base is installed on the guide frame. The upper and lower mold bases are matched and installed. An injection zone is installed at the bottom of the upper mold base, and a feed pipe is installed at the top of the upper mold base. This improves cooling efficiency and thus demolding efficiency.

[0004] However, due to the fixed specifications of the lower and upper mold bases, only one type of toy can be injection molded at a time, resulting in low practicality. Furthermore, after injection molding, the finished toy adheres to the inner wall of the injection cavity, making it inconvenient to remove.

[0005] Therefore, we propose a mold for plastic toys that is easy to demold. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a mold for plastic toys that is easy to demold, solving the problems of low practicality and inconvenient removal of existing devices.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a mold for plastic toys that is easy to demold, including a base, wherein four sets of hydraulic telescopic rods with opposite positions are fixedly installed on the top surface of the base, and a top seat is fixedly installed on the top of the hydraulic telescopic rods;

[0008] The top surface of the base is equipped with three sets of lower molds in opposite positions. The top surface of each lower mold has a through lower mold cavity. A matching mounting frame A is fixedly installed on the outer wall of the lower mold. The top surface of the mounting frame A has four sets of mounting holes A. The top surface of the base has twelve sets of threaded holes in opposite positions. The bottom surface of the top seat is equipped with three sets of upper molds in corresponding specifications. The bottom surface of each upper mold has a matching upper mold cavity. A mounting frame B is fixedly installed on the outer wall of each upper mold. The bottom surface of the mounting frame B has four sets of mounting holes B. The top surface of the top seat is equipped with three sets of injection ports in opposite positions. The top surface of the upper mold cavity has an injection hole that communicates with the injection ports.

[0009] Three sets of electrically operated telescopic rods are fixedly installed on the top surface of the base. The telescopic ends of the electrically operated telescopic rods are equipped with base plates that are compatible with the specifications of the lower mold cavity. The base plates are located inside the lower mold cavity and are connected to the electrically operated telescopic rods through slots.

[0010] Preferably, the top surface of the lower mold is fixedly equipped with two sets of positioning rods in opposite positions, and the bottom surface of the upper mold is provided with two sets of positioning holes of matching specifications. This allows for the positioning of the lower mold and the upper mold, improving accuracy.

[0011] Preferably, a dry ice control processor is fixedly installed on the rear side of the base, and a dry ice cylinder is assembled inside the dry ice control processor. A spray plate connected to the dry ice cylinder is fixedly installed on the rear side of the top surface of the base. The spray plate has evenly distributed spray holes on its front side, which can cool the upper mold and the lower mold and improve the efficiency of injection molding.

[0012] Preferably, the top surface of the dry ice control processor is equipped with control buttons, which facilitates its control.

[0013] Preferably, baffles A, which are fitted onto the cylinder output end, are slidably connected to the left and right sides of the top surface of the base, and baffles B, which are fitted onto the cylinder output end, are slidably connected to the front side of the top surface of the base. This allows them to form a frame with the spray plate, thereby improving the cooling effect.

[0014] Preferably, the bottom surface of the base is fixedly equipped with four sets of oppositely positioned pads, which can improve the overall stability.

[0015] This is a mold for plastic toys that is easy to demold. By setting up mounting frame A, threaded holes and mounting frame B, the mounting holes A on mounting frame A correspond to the threaded holes. Then, the lower mold is connected and fixed to the base with bolts. The upper mold is connected to the top seat through mounting frame B. The installation and disassembly are simple and convenient. Different specifications and shapes of upper and lower molds can be replaced to produce toys of different shapes and improve practicality.

[0016] 2. Simultaneously, through the setting of electric telescopic rod and base plate, after injection molding is completed, the hydraulic telescopic rod first drives the top seat and upper mold to move upward, and then the electric telescopic rod drives the base plate to move upward, thereby ejecting the finished product in the lower mold cavity, making it simple and convenient to remove.
