Description

Technical Field

[0001] The utility model relates to the technical field of injection molding auxiliary devices, in particular to an injection molding device for PC transparent plastic products with auxiliary functions. Background Art

[0002] Plastic molding is a method for producing industrial products. Products are usually produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding and die casting. Injection molding machines are the main molding equipment used to make various shapes of plastic products using plastic molding molds from thermoplastics or thermosetting materials. However, existing plastic product injection molding equipment often lacks corresponding auxiliary equipment for more reasonable assistance.

[0003] Existing plastic product injection molding equipment lacks corresponding auxiliary equipment, resulting in an overall slow molding speed, making the entire equipment unsuitable for large-scale production. Existing plastic product injection molding equipment is difficult to quickly collect plastic products after molding, which is not conducive to the subsequent work.

[0004] For example, Chinese patent CN212764457U discloses an auxiliary device for plastic product injection molding equipment. Through a water tank, a spiral conduit, and a condenser, the plastic products can be quickly cooled during the injection molding process, thereby avoiding the time-consuming natural cooling process, improving the efficiency of the equipment, and allowing the plastic products to be quickly molded. Through the through-hole, the push plate, and the holding box, the molded plastic products can better fall into the interior of the holding box, thereby achieving the purpose of rapid collection.

[0005] However, when the device is used to injection-mold PC transparent plastic products, the molded plastic products will adhere to the inside of the molding module and need to be picked out by workers by hand, thus affecting the production efficiency of the plastic products.

[0006] For this reason we urgently need to provide an injection molding device for PC transparent plastic products with auxiliary functions. Utility Model Content

[0007] The purpose of the present utility model is to provide an injection molding device for PC transparent plastic products with auxiliary functions, so as to solve the problem raised in the above-mentioned background technology that when PC transparent plastic products are injection molded, the molded plastic products will adhere to the inside of the molding module, requiring workers to pick them out by hand, thereby affecting the production efficiency of the plastic products.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an injection molding device for PC transparent plastic products with auxiliary functions, comprising a connecting plate, support legs, side panels, a telescopic member and a molding module, wherein the support legs are fixedly installed around the bottom of the connecting plate, the side panels are fixedly installed on the left and right sides of the top of the connecting plate, the telescopic member is fixedly installed on the front and rear ends of one side adjacent to the left and right side panels, the molding module is fixedly installed at the output end of the telescopic member, and auxiliary devices are provided at the upper and lower ends of the connecting plate.

[0012] Preferably, the cooling unit includes a cooling box, a pump body, a water inlet pipe, a cooling pipe, a water outlet pipe and a condenser. The cooling box is installed on the top of the molding module, the pump body is installed on the front of the cooling box, the water inlet pipe is connected to the output end of the pump body, the cooling pipe is connected to one end of the water inlet pipe and is located inside the molding module, the water outlet pipe is connected to the end of the cooling pipe away from the water inlet pipe, and the condenser is installed on the outside of the water outlet pipe.

[0013] Preferably, a cavity is opened on the left side inside the molding module, and the cooling pipe is coiled inside the molding module. By starting the pump body, cold water in the cooling box is pumped into the cooling pipe. When the cold water flows in the cooling pipe, the molten plastic in the molding module is cooled, thereby accelerating the molding of plastic products.

[0014] Preferably, a rectangular groove of the same size as the push plate 1 is opened inside the molding module. When the stop block abuts against the inner wall of the cavity opened by the molding module, the push plate 1 is just flush with the inner surface of the molding module, preventing the push plate 1 from protruding and affecting the injection molding of the plastic product.

[0015] Preferably, a connecting hole of the same size as the connecting rod is opened on one side of the forming module, the diameter of the stop block is larger than the diameter of the connecting hole, and the spring is always in a compressed state.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This injection molding device for PC transparent plastic products with auxiliary functions is equipped with a pushing unit. When the molded plastic product adheres to the inside of the molding module, as the molding module moves toward the side plate, the disc will contact the side plate, so that the disc pushes the connecting rod to drive the pushing plate to move, pushing the plastic product inside the molding module out, thereby facilitating demolding. This solves the problem raised in the background art that when injecting PC transparent plastic products, the molded plastic product will adhere to the inside of the molding module, requiring workers to manually pick it out, thereby affecting the production efficiency of the plastic product.

[0019] 2. The injection molding device for PC transparent plastic products with auxiliary functions is provided with a collection unit. When the molded plastic products fall into the collection box for collection, the rubber pad on the guide plate cushions the falling plastic products, and then the plastic products slide along the guide plate into the collection box for collection. At the same time, the push plate 2 is pushed by the telescopic part 2 to push the plastic products accumulated on the right side of the collection box to the left side of the collection box, thereby increasing the number of plastic products that can be held in the collection box.
