Description

Technical Field

[0001] This utility model belongs to the field of molding equipment, and specifically relates to a molding device for pet chew toys. Background Technology

[0002] Toy molding equipment is a type of machinery used to process raw materials (plastics, rubber) into specific pet toy shapes. During operation, the relative motion between components in current toy molding equipment generates inertial impact forces during mold opening and closing, material transfer, and other processes. For example, in injection molding, the rapid downward pressure of the upper mold to close the mold, without cushioning, can cause slight misalignment between molds, resulting in dimensional deviations in the toy. To address this, some manufacturers reduce the equipment's operating speed to decrease the impact force. However, while this conventional method can mitigate the impact to some extent, it significantly reduces production efficiency and cannot meet the demands of large-scale production. Furthermore, prolonged operation without limiting and cushioning causes frequent wear and tear on components due to impacts, shortening equipment lifespan, increasing maintenance costs and downtime, and negatively impacting overall production efficiency. Therefore, a new structure is needed to solve these technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3As the first embodiment of this utility model: a pet biting toy molding device, including: a lower mold assembly, an upper mold assembly and a mold assembly, a mold assembly for injection molding the toy is installed between the upper mold assembly and the lower mold assembly, the lower mold assembly includes a base plate 100 for mounting a base block 110, a buffer member 130 is installed on the upper surface of the base plate 100 through a base plate 2 120, the mold assembly is installed on the upper surface of the lower mold assembly, the mold assembly includes a mounting plate 200 and a mold plate 210, the mold plate 210 is installed on the upper surface of the mounting plate 200, the upper mold assembly includes a cover plate 300, an upper mold body 310 for closing with the mold plate 210 is installed on the lower surface of the cover plate 300, and movable members for guiding and limiting are installed on the outer surfaces of the lower mold assembly and the upper mold assembly; A base block 110 is installed on the left and right edges of the upper surface of the base plate 100. A base plate 2 120 is installed between the two base blocks 110 via the base plate 100. A buffer 130 is installed at each of the four corners of the upper surface of the base plate 2 120. The buffer 130 is a spring damping buffer. An mounting plate 200 is installed on the upper surface of the two base blocks 110. The buffer 130 penetrates the lower surface of the mounting plate 200. The lower surface of the mold plate 210 is connected to the top of the buffer 130. A gap is provided between the mold plate 210 and the mounting plate 200. A mold groove 211 matching the structure of the molded toy is opened downward at the center of the upper surface of the mold plate 210. Two buffer pillars 220 are symmetrically installed on the left and right edges of the upper surface of the mold plate 210. A column 230 is installed through each of the four corners of the upper surface of the mold plate 210. The lower end of the column 230 is connected to the upper surface of the base block 110. A cover plate 300 is installed at the end of the four columns 230 away from the lower mold assembly. The upper mold body 310 is installed through the column 230 below the cover plate 300. The lower surface of the upper mold body 310 is recessed upward to form a symmetrical structure that matches the mold groove 211. The lower surface of the upper mold body 310 is provided with a groove for inserting the buffer post 220. The depth of the groove matches the extension and retraction of the buffer post 220. The front and rear surfaces of the upper mold body 310 are respectively provided with two injection holes 320 for injection molding. The moving parts include rack driver 1, rack driver 2 410 and rack body 420. In use, the user first sets the mold groove 211 on the upper surface of the mold plate 210 and the lower surface of the upper mold body 310 according to actual production needs to form the toy structure to be injection molded. This is not limited to a specific structure; the user can choose according to the actual situation. After setting, the user can activate the movable part, causing it to move. This causes the upper mold body 310 on the lower surface of the cover plate 300 to move downwards along the column 230 until the upper mold body 310 abuts against the mold plate 210, achieving the mold closing effect. At this time, the user can perform injection molding through the injection molding part on the outer surface of the upper mold body 310 (injection molding is existing technology; its specific working principle and structure are not described here). When the mold closes, the upper mold body 310 will make hard contact with the mold plate 210 through the movable part. At this time, the lower surface of the mold plate 210... Both the buffer component 130 and the buffer pillar 220 on the upper surface of the mold plate 210 can buffer this hard contact (both the buffer pillar 220 and the buffer component 130 are damping spring buffers, which will not affect the mold closing due to the reaction force of the spring; the specific working principle and structure are common knowledge and will not be elaborated here), thereby protecting the mold plate 210 and the upper mold body 310 and increasing their service life. After the mold closing and injection molding are completed, the user can reverse the above operation to cool and remove the injection-molded pet toy. During use, by setting the lower mold assembly, the upper mold assembly, and the injection molding mold assembly between the two, the precise mold closing and stable locking of the upper and lower molds, combined with the specific cavity of the mold assembly, ensures that the raw material is fully filled and accurately molded during the high-pressure injection molding process, thus ensuring the consistency and precision of the toy's shape.

[0020] Please see Figures 1 to 3 As a second embodiment of the present invention: based on the description in the above embodiments, further, rack driver one and rack driver two 410 are respectively installed on the left and right surfaces of the upper mold body 310 and the mold plate 210, and a rack body 420 for driving mold closing is installed between rack driver one and rack driver two 410. The movable parts also include a limiting plate 400 and a positioning post. Two limiting plates 400 are symmetrically installed on the front and rear surfaces of the upper mold body 310. A strip-shaped through hole 401 is opened at the center of the front surface of the limiting plate 400. A positioning post is inserted through the front and rear surfaces of the mold plate 210. The positioning post is movably set inside the strip-shaped through hole 401 of the limiting plate 400. In use, when operating according to the steps of the first embodiment, the limiting plate 400 inside the moving part slides up and down in conjunction with the positioning post on the front surface of the mold plate 210, thereby ensuring stable movement between the upper mold body 310 and the mold plate 210. When the upper mold body 310 and the mold plate 210 are in the mold closing operation, the rack driver 2 410 on the outer surface of the mold plate 210 drives the internal rack body 420 to move up and down, thereby cooperating with the rack driver 1 to drive the upper mold body 310 to move up and down along the column 230, thereby enabling the upper mold body 310 and the mold plate 210 to perform the mold closing operation (rack). The drive unit 1, the rack and pinion drive unit 2 410, and the rack body 420 are existing technologies, and their specific working principles and structures will not be described in detail here. During use, the guide and limit movable parts installed on the outer surfaces of the lower mold assembly and the upper mold assembly can accurately constrain the relative movement trajectory of the upper and lower molds during the operation of the device, avoiding deviation or misalignment during mold closing, ensuring tight closure of the mold assembly, reducing material leakage and flash generation, improving the precision of injection molding and the product qualification rate, reducing mold wear caused by collision, and making the opening and closing of the upper and lower molds smoother and more stable, which helps to extend the service life of the device and ensure the stability and safety of the production process.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
