Technical Field
[0001] The utility model relates to the technical field of mold slide structures, in particular to an oblique elastic slide structure of a mold. Background Art
[0002] When using molds for production, the existing technology generally uses an oil cylinder to demould the product. When the oil cylinder is demoulded as a whole, due to the large demoulding area, the force is uneven during the demoulding process, which can easily cause the product to deform and reduce the product qualification rate.
[0003] After searching, the existing Chinese patent publication number: CN115782076A is a mold slide anti-retreat structure and an injection mold, including a slide seat, a pressure block, the pressure block is at least partially arranged above the slide seat, including a pin and a pusher, a sliding groove is arranged on the outward side of the slide seat, and a mounting hole is arranged on one side or both sides of the slide seat located at the sliding groove. The length of the pin is greater than the length of the mounting hole. The pin passes through the mounting hole and can be movably assembled on the slide seat. A clamping slot is arranged on the pressure block, and the pin is clamped in the clamping slot. The movable end of the pusher is placed in the sliding slot and abuts on the pin. A pin is arranged on the slide seat, and an oil cylinder or an air cylinder abuts on the pin to clamp the pin in the clamping slot to prevent the slide seat from retreating due to the impact of injection pressure. The slide seat is firmly assembled on the rear template. In the mold opening state, the oil cylinder pulls the slide back, and the pin is disengaged from the clamping slot to demold the slide.
[0004] The cited patent document also has the same problem. When a hydraulic cylinder is used to demould the product, the large demoulding area and uneven force during the demoulding process can easily cause deformation of the product and reduce the qualified rate of the product.

Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.
[0034] The mold oblique elastic slide structure of the preferred embodiment of the utility model is as follows Figure 1-Figure 5As shown, it includes a front mold component 1 and a mold core chamber 2 located inside the front mold component 1, and slide mold cavities 3 are arranged on both sides of the mold core chamber 2. The interior of each slide mold cavity 3 is elastically and slidably connected with a slide insert 4. The inner bottom wall of the slide mold cavity 3 and the bottom surface of the slide insert 4 are symmetrically provided with a plurality of spring mounting holes 13, and a plug screw hole is longitudinally penetrated in each spring mounting hole 13.
[0035] Specifically, multiple groups of spring mounting holes 13 are arranged on the inner bottom wall of the slide mold cavity 3 and the bottom surface of the slide insert 4, and two opposite ones are symmetrically flush.
[0036] In this embodiment, an elastic limiting sliding core pulling assembly 10 for the sliding insert 4 to bounce open is arranged between the bottom surface of the sliding insert 4 and the top surface of the sliding ejection cavity 3. The elastic limiting sliding core pulling assembly 10 includes a spring component 12 adapted to be installed in a spring installation hole 13 inside the sliding ejection cavity 3 and a plug screw component 11 extending from the bottom of the front mold component 1 through the plug screw hole to the sliding insert 4. The spring component 12 is sleeved on the circumferential side of the plug screw component 11.
[0037] Specifically, when the driving screw 11 is inserted into the front mold component 1 through the driving screw hole, the spring component 12 is sleeved on the peripheral side of the driving screw 11, and the two ends of the spring component 12 are respectively placed in the spring mounting holes 13 opposite to the inner bottom wall of the slide mold cavity 3 and the bottom surface of the slide insert 4, so as to effectively limit the spring component 12 and prevent it from falling off.
[0038] In the present embodiment, auxiliary limiting sliding components 7 are provided on both sides of the slide insert 4 and inside the front mold component 1. The auxiliary limiting sliding components 7 include two inclined guide sliding blocks 5 symmetrically inserted into the front mold component 1. At the same time, the two inclined guide sliding blocks 5 are respectively slidably connected to the outer walls of the slide insert 4 on both sides. The outer walls of the slide insert 4 on both sides are provided with slide guide grooves 14. The opposite sides of the two inclined guide sliding blocks 5 are provided with slide guide strips 15 that are adapted to be slidably connected to the slide guide grooves 14. When each inclined guide sliding block 5 is inserted into the front mold component 1 along the slide guide groove 14, the top surface of the inclined guide sliding block 5 is fixedly connected to the front mold component 1 by screws.
[0039] Specifically, the inclined guide slide block 5 is installed against the slide guide groove 14 and fixed on the front mold component 1 with screws. It can not only limit the spring-opening stroke of the slide insert 4, but also clamp the slide insert 4, thereby preventing the slide insert 4 from tilting and improving the positioning accuracy.
[0040] In this embodiment, when the front mold part 1 is demolded, the elastic limit slide core pulling assembly 10 releases the elastic force to drive the slide insert 4 to bounce open along the slide demolding slope in the slide demolding cavity 3, and a buckle assembly 9 is installed between the slide insert 4 and the rear template to prevent the slide insert 4 from loosening during injection. The buckle assembly 9 includes a plurality of slide fasteners 8 symmetrically installed on the top surface of the slide insert 4 and a plurality of B-plate reverse fasteners 16 fixedly installed on the rear template. The B-plate reverse fasteners 16 are inserted into the slide insert 4 through the locking connecting rod 17. When the front mold part 1 is closed, the slide insert 4 is pressed and reset, and the slide fasteners 8 on the slide insert 4 are matched and buckled with the B-plate reverse fasteners 16, and buckle installation openings 6 for installing the slide fasteners 8 and the B-plate reverse fasteners 16 are symmetrically opened on the top surface of the slide insert 4.
[0041] Working principle:
[0042] The oblique elastic slide structure of the mold has a spring member 12 installed at the bottom of the slide insert 4. When the front and rear molds are separated, the spring member 12 will bounce the slide insert 4 along the oblique guide slider 5. Because the product is adhered to the rear mold core, when the front and rear molds are opened, the demoulding of the product and the front mold component 1 and the slide insert 4 are ejected and the core pulling action are completed synchronously. The plug screw member 11 can control the ejection position (slide core pulling distance) of the slide insert 4. When the front and rear molds are closed, the rear mold will press the slide insert 4 back to the original position and buckle it with the B plate buckle 16 to prevent the slide from loosening and causing dislocation during injection.
[0043] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
