[0023] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0024] like Figures 1 to 7 As shown, in this embodiment, a mold with an added side mold cavity comprises a front template 1, a rear template 2, a mold bottom plate 3, an inner slider 4 and a T-slot drag blade 5. A front mold core 6 is installed in the middle of the lower end of the front template 1, the rear template 2 is located above the mold bottom plate 3, and a rear mold core 7 is arranged in the middle of the upper end of the rear template 2. The upper end of the T-slot drag blade 5 is inserted into the rear mold core 7, and a T-shaped slide groove 8 is arranged on the inner side of the T-slot drag blade 5. The upper end depth of the T-shaped slide groove 8 is greater than the lower end depth of the T-shaped slide groove 8, and recessed slide grooves 9 are arranged on both sides of the T-shaped slide groove 8. The inner slider 4 moves laterally on the rear mold core 7, and the inner slider 4 slides on the T-shaped slide groove 8 along the vertical direction. The two sides of the inner slider 4 are clamped in the recessed slide groove 9, and a mold cavity protrusion 10 is arranged on the outer side of the upper end of the inner slider 4. A product molding position 11 is formed between the upper end of one inner slider 4 and the upper end of another inner slider 4.

[0025] The product is injection molded in the product molding position 11. When it is demolded after cooling, the front template 1 and the rear template 2 are separated in the vertical direction, so that the front mold core 6 is separated from the rear mold core 7, and the product in the product molding position 11 will remain on the rear mold core 7. The T-slot shovel 5 is pulled downward by the mold bottom plate 3. During the downward movement of the upper end of the T-slot shovel 5, due to the restriction of the inner slider 4 in the recessed slide groove 9, and the inner slider 4 is also restricted in the lateral direction by the rear mold core 7, when the T-slot shovel 5 is disengaged, the inner slider 4 is restricted to move along the T-shaped slide groove 8. Because the upper end depth of the T-shaped slide groove 8 is greater than the lower end depth of the T-shaped slide groove 8, the inner slider 4 gradually moves along the upper end of the T-slot shovel 5, widens the distance between it and the product, forms a horizontal separation with the product, and can be demolded in the longitudinal and lateral holes at one time.

[0026] A filling nozzle 12 is provided in the middle of the upper end of the front template 1, and a flow channel 13 is connected to the lower end of the filling nozzle 12. The flow channel 13 flows to the product forming position 11, and the fluid is injected from the filling nozzle 12. The fluid is guided by the flow channel 13 to form the structure of the product in the product forming position 11.

[0027] A support plate 14 is arranged below the rear template 2, the lower end of the T-slot drag shovel 5 is fixed on the support plate 14, a return spring 15 is connected between the support plate 14 and the mold bottom plate 3, an ejector panel 16 and an ejector bottom plate 17 are arranged on the mold bottom plate 3, an ejector rod 18 is arranged on the ejector bottom plate 17, the ejector rod 18 passes through the ejector panel 16 and is upwardly connected to the support plate 14, the return spring 15 surrounds the outer side of the ejector rod 18, a travel limit block 19 is arranged on the side of the rear template 2, the lower end of the travel limit block 19 is fixed on the support plate 14, the upper end of the travel limit block 19 is movable on the rear template 2, a plurality of support columns 20 are arranged between the support plate 14 and the mold bottom plate 3, the support columns 20 pass through the ejector panel 16 and the ejector bottom plate 17.

[0028] During mold closing, the support plate 14 is supported by the support column 20, and the rear template 2 is supported by the support plate 14. During demolding, the stroke limit block 19 is pulled downward, but the rear template 2 limits the stroke of the stroke limit block 19, resulting in that the rear template 2 and the support plate 14 will not be completely separated, which has a good effect on the subsequent mold closing and alignment. At the same time, the ejector base plate 17 and the ejector panel 16 limit the position of the ejector rod 18, guide the disengagement direction of demolding, and then the return spring 15 is used to pull the support plate 14 and the mold base plate 3 back together.

[0029] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
