Description

Technical Field

[0001] This utility model relates to the field of material positioning technology for plastic molding machines, and more specifically, to a plastic molding machine with a positioning structure. Background Technology

[0002] Plastic molding machines are a type of plastic molding and processing equipment developed based on rubber machinery and metal die-casting machines.

[0003] Currently, the material positioning device of commonly used plastic molding machines is located below the fixed mold. During the product demolding process, the product may fall away from the material positioning device and need to be collected manually. In addition, the fixed material positioning device lacks flexibility. For example, a plastic molding machine with a positioning structure disclosed in CN218227571U includes an injection molding machine body. A pushing device is fixedly installed at one end of the bottom of the injection molding machine body, and a fixed guide rail is fixedly installed at the other end of the bottom of the injection molding machine body. A collecting device is movably installed inside the fixed guide rail, and a material positioning device is fixedly installed at one end of the top of the injection molding machine body.

[0004] As can be seen from the above-disclosed scheme, the material unloading and positioning device is located below the fixed mold. When the molded product does not demold smoothly from the moving mold, it will cause the product to be pulled to the left and out of the area above the material unloading and positioning device. As a result, the demolded product will fall onto the plastic molding machine and then be manually collected, which poses a safety hazard. At the same time, it reduces the comprehensiveness of the collection of molded products. Furthermore, the fixed material unloading and positioning device is not convenient for quick adjustment of the support height or for moving to other machines, which reduces its flexibility of use. Moreover, after the collection device is full, manual intervention is required to collect the molded products, which increases the collection steps and reduces the collection efficiency. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a plastic molding machine with a positioning structure. This plastic molding machine with a positioning structure, through the setting of a hopper, receiving trough, and guide trough, can not only increase the comprehensiveness of the collection of molded products, but also export the collected molded products, making it convenient for workers to collect safely and improving the ease of use. Furthermore, through the setting of a fixing rod, suction block, adjusting rod, support rod, and positioning pin, the support height of the hopper can be quickly adjusted, and the product positioning mechanism can be easily moved to other plastic molding machines for use, greatly improving its flexibility of use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A plastic molding machine with a positioning structure includes a plastic molding machine body, on which a moving mold and a fixed mold are detachably connected. A base is fixedly connected to the bottom of the plastic molding machine body, and a product positioning mechanism is movably connected to the surface of the base. The product positioning mechanism is located directly below the moving mold and the fixed mold after mold closing. The product positioning mechanism includes a hopper and a positioning frame. One end of the hopper has a receiving groove, and the bottom of the receiving groove is fixedly connected to a guide groove. This plastic molding machine with a positioning structure, through the hopper, receiving groove, and guide groove, not only increases the comprehensiveness of product collection but also allows the collected products to be discharged, facilitating safe collection by workers and improving ease of use. Furthermore, through the fixed rod, suction block, adjusting rod, support rod, and positioning pin, the support height of the hopper can be quickly adjusted, and the product positioning mechanism can be moved to other plastic molding machines for use, greatly improving its operational flexibility.

[0008] Furthermore, the positioning frame includes a fixed frame, the inner wall of which is fixedly connected to the surface of the hopper, and three support rods and an adjusting rod are fixedly connected to the bottom of the fixed frame. The adjusting rod has an adjusting hole on its surface, and the inner wall of the adjusting hole is detachably connected to the surface of the positioning pin, so as to facilitate quick positioning of the lifting height of the fixed frame through the positioning pin and the corresponding height adjusting hole.

[0009] Furthermore, an anti-detachment block is fixedly connected to one end of both the support rod and the adjusting rod. The bottom of the anti-detachment block is provided with a first limiting groove. The anti-detachment block is made of elastic wear-resistant rubber. The anti-detachment block has the function of preventing detachment and can also prevent the support rod and the adjusting rod from extending and retracting arbitrarily.

[0010] Furthermore, a fixed rod is slidably connected to one end of both the support rod and the adjusting rod. A sliding hole is opened at one end of the fixed rod, and a storage groove is fixedly connected to one end of the sliding hole. The inner wall of the storage groove is movably connected to the surface of the anti-detachment block. The storage groove facilitates the storage of the support rod and the adjusting rod, thereby adjusting the support height.

[0011] Furthermore, a second limiting groove is provided at the bottom of the storage slot, and a spring is movably connected to the inner wall of the second limiting groove. The other end of the spring is movably connected to the inner wall of the first limiting groove. The spring is in a compressed state, which enables the support rod and the adjusting rod to automatically extend upward.

[0012] Furthermore, a positioning pin is inserted into the surface of the fixing rod, a pad is fixedly connected to one end of the fixing rod, and an adsorption block is fixedly embedded in the bottom of the pad. The adsorption block is made of a strong magnet and can be adsorbed and fixed to the surface of the base by magnetic adsorption force, which facilitates the rapid movement and positioning of the product positioning mechanism.

[0013] Furthermore, the guide channel is provided with a guide section and a collection section. The guide section is inclined to facilitate the flow of the collected molded products to the collection section, and then away from the side of the plastic molding machine. This makes it easier for the user to collect the products from outside the machine, thus improving the safety of use.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution, through the setting of the dropping hopper, receiving trough and guide trough, can not only increase the comprehensiveness of the collection of the formed products, but also export the collected formed products, which is convenient for staff to collect safely and improves the ease of use.

[0016] (2) This solution, through the setting of fixed rods, suction blocks, adjusting rods, support rods and positioning pins, can not only quickly adjust the support height of the hopper, but also facilitate the product positioning mechanism to be moved to other plastic molding machines for use, which greatly improves its flexibility of use.
