[0002] Plastics are polymer compounds made from monomers through polyaddition or polycondensation reactions. They have a medium deformation resistance, somewhere between that of fiber and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The primary component of plastic is resin. Resin refers to polymer compounds that have not been mixed with various additives. The term originally derives from the lipids secreted by plants and animals.

[0045] Working principle: The opening and closing mold of plastic products is a complex and sophisticated system. Its working principle involves the coordinated operation of many structures. First, the positioning ring 1 enables the center of the injection nozzle to quickly connect with the center of the mold gate sleeve to ensure accurate injection of the injection material. The heat insulation plate 2 reduces the heat transferred from the mold to the mounting plate to maintain the stable performance of the mounting plate. The front mold mechanical plate 3 and the rear mold mechanical plate 11 respectively fix the front template 5 and the rear template 6 when opening and closing the mold on the injection molding machine table. The hot runner plate 4 is used to place the hot runner equipment to provide stable conditions for the injection of plastic. The front template 5 and the rear template 6 cooperate with each other to complete the molding of the product. The push plate 7 controls the rear mold insert 52 to pull the core before the ejection movement to prepare for the smooth ejection of the product. The square iron 8 fixes and supports the mold B plate to withstand the huge pressure during the injection molding process. The needle plate 9 places and fixes the ejector pin 53, and the needle base plate 10 supports the ejector pin 53. The ejector pin 53 is lifted and moved upward by the ejector rod to realize the separation of the product from the template. The wiring slot 12 connects the heating wire and temperature sensing wire of the hot runner system, and cooperates with the temperature control box to control the heating to ensure the appropriate temperature during the injection molding process.

[0046] The locking module 13 then protects the mold by preventing the movable and fixed molds from opening during lifting, loading, unloading, and transportation. The side lock 14 prevents the guide post 17 from loosening due to prolonged friction, corrects the mold center, and prevents misalignment of the front and rear molds. The L-type travel lever latch 15 cooperates with the travel switch 16 for sensing, which limits the position and travel of the mechanical movement. The guide post 17 ensures the mold moves with precise positioning and guides the mold stroke. The slide 18 moves laterally when the front and rear molds open horizontally, driving the slider 20 to disengage the product latch. The shovel 19 drives the slider 20 to its full reset position and moves it backward when the mold is opened. The slider 20 can slide perpendicular to the direction of mold opening and closing or at a certain angle to the direction of mold opening and closing. The pressure strip 21 suppresses and positions the movement track of the slider 18, and the guide sleeve 22 protects the shaft from wear. The mold foot 23 protects the external parts of the mold, keeping it flush with the mechanical plate for easy upper and lower molds. The front mold clamp 24 squeezes the mold core to stabilize and secure the workpiece. The limit clamp 25 limits the sliding stroke of the slide 18, the front mold wear-resistant plate 26 reduces the wear of large parts, the guide block 27 guides the slide 18 to move in a certain direction, and the front mold bevel 28 reduces the mold size and reduces costs. The front mold core 29 determines the mold shape structure of the product's appearance and exterior surface. The counter 30 accurately counts, locates and monitors the produced mold. The bevel pressure plate 31 prevents the pressed workpiece from vibrating and moving during the production process. The hot nozzle protection sleeve 32 protects the hot nozzle from friction loss during the production process. The spring seat 33 places and fixes the spring, the latch machine sliding groove 34 allows the object to slide along the specified position, the sliding groove retaining block 35 fixes the position of the latch machine sliding groove 34, and the sliding rod guide block 36 guides the sliding rod to move in a certain direction. The latch machine sliding rod 37 moves in a certain direction, driving the flat key 38 to enter the key slot, reducing the resistance of the front and rear templates to achieve mold opening, and the flat key 38 increases the mold opening resistance of the front and rear templates, causing them to delay movement;

[0047] Secondly, the stop block 39 presses the flat key 38 to prevent it from moving around, the reset block 40 presses the spring of the positioning block 42 to reset it, the fixing block 41 places other parts of the button machine, and the positioning block 42 is fixed with a certain inclination to play a delay role. After the stroke adjustment block 43 moves to a certain distance, it rubs and squeezes with the positioning block 42 to pull it away from the rear template 6. The reset block 44 resets the stroke adjustment block 43, and the button machine pull rod 45 pulls the stroke adjustment block 43 to move, causing the positioning block 42 to retreat, and the rear mold squeezing block 46 squeezes the mold core to achieve stability and fixation of the workpiece. The rear mold core 47 is the most precise part of the mold processing, which determines the important size and structure of the product. The rear mold wear-resistant plate 48 reduces the wear of large parts, the circular positioning 49 ensures the precise positioning between the front and rear molds, the sleeve 50 is used for the inner hole, and the sleeve plays a role in ejection;

[0048] Finally, the runner insert 51 ensures the accuracy and smoothness of the runner, the rear mold insert 52 plays the role of venting and core pulling, the ejector pin 53 ejects the product, and the return pin 54 guides the ejector pin 53 when it is ejected and retreated, ensuring that the needle plate 9 retreats into place. Spring 1 55 ensures the reset of the ejector pin 53 after ejecting the product, spring 2 56 assists the push plate 7 to retreat, the support pin 57 limits and supports the spring, the support column 58 bears and transmits the gravity load of the mold, and the limit block 59 limits the ejection stroke. The middle support 60 guides the reciprocating motion of the needle plate 9, and the equal height screw 61 fixes the position of the needle plate 9 and other components in the mold. The garbage pin 62 cooperates with the pressure plate 63 to support the needle plate 9 to prevent garbage accumulation from causing deformation of the needle plate 9. In short, based on the opening and closing mold of plastic products, each structure performs its own function and cooperates closely to complete the efficient and precise production of plastic products.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
