[0044] Embodiment 2

[0046] Specifically, the auxiliary piece 202 further comprises a fixed connecting rod 202e, one end of the fixed connecting rod 202e is fixedly connected to the surface of the sleeve ring 202d, and a synchronous pipe 202f is fixedly connected to the surface of the fixed connecting rod 202e.

[0047] The displacement of the sleeve ring 202d causes the fixed connecting rod 202e to be displaced synchronously, so as to drive the synchronous pipe 202f to be displaced synchronously

[0048] Specifically, the adjusting assembly 200 further comprises a telescopic piece 203, the telescopic piece 203 comprises a push rod 203a, the end of the push rod 203a is fixedly connected with a blocking lug 203b, the surface of the injection molding lug 201a is further provided with a push stop groove 201a-5, the blocking lug 203b is slidingly arranged in the push stop groove 201a-5, a second spring 203c is sleeved on the surface of the push rod 203a, the second spring 203c is in a stretched state, and one end of the second spring 203c is fixedly connected to the bottom of the blocking lug 203b.

[0049] The push rod 203a can slide in the synchronization tube 202f, when the push rod 203a is deep into the bottom of the synchronization tube 202f, the synchronization tube 202f displacement can push the push rod 203a to displace, the blocking protrusion 203b slides in the push stop slot 201a-5, under the pushing of the push rod 203a, the blocking protrusion 203b pushes out of the push stop slot 201a-5, and after the blocking protrusion 203b is reset under the reset action of the second spring 203c, the blocking protrusion 203b can re-enter the push stop slot 201a-5 to reset.

[0050] Specifically, the telescopic piece 203 further comprises a sleeve 203d, the push rod 203a is slidably connected in the sleeve 203d, the sleeve 203d is provided with a spring slot 203d-1, and the other end of the second spring 203c is fixedly connected to the bottom of the spring slot 203d-1.

[0051] The sleeve 203d is internally provided with the spring slot 203d-1, which can be used for placing the second spring 203c, and after the push rod 203a is displaced, the second spring 203c is fixedly connected to the spring slot 203d-1 in the sleeve 203d, so that the second spring 203c resets the push rod 203a.

[0052] Specifically, the sleeve 203d is fixedly provided with a fixed ring 203e, the surface of the sleeve 203d is sleeved with a third spring 203f, the third spring 203f is in a compressed state, the injection protruding plate is further provided with a stretching slot 201a-6, the sleeve 203d slides in the stretching slot 201a-6, one end of the third spring 203f is fixedly connected to the surface of the fixed ring 203e, and the other end of the third spring 203f is fixedly connected to the stretching slot 201a-6.

[0053] The fixed ring 203e is used for connecting the third spring 203f, so that the third spring 203f can push the fixed ring 203e, so that the upper end of the sleeve 203d abuts against the end of the stretching slot 201a-6, and when the pressure of the injection cavity increases, the spring can be forced to be compressed, so that the sleeve 203d slides, drives the push rod 203a and the blocking protrusion 203b to displace, so that the liquid injection material can smoothly pass through the flow-through slot 201a-3 into the injection cavity.

[0054] Embodiment 3

[0055] Referring to Figures 1-7 As a third embodiment of the utility model, the embodiment is based on the first two embodiments.

[0056] Specifically, the number of the auxiliary connecting rods 202c is two, the number of the fixed connecting rods 202e is four, and the four fixed connecting rods 202e jointly act in four groups, and each group is provided with one fixed connecting rod 202e and three telescopic pieces 203.

[0057] Four fixed connecting rods 202e are provided on the surface of the collar 202d, which are divided into four groups and work together so that they can work synchronously under the action of the auxiliary connecting rod 202c.

[0058] When in use, the injection molding concave plate 101 and the injection molding middle plate 102 are pressed against one side of the injection molding convex plate 201a. The injection molding middle plate 102 first contacts and pushes the auxiliary rod 202a, and the first spring 202b is stretched and pushes the auxiliary connecting rod 202c, driving the collar 202d to move synchronously. The displacement of the collar 202d will drive the fixed connecting rod 202e to move synchronously. The synchronization tube 202f fixed on the surface of the fixed connecting rod 202e is separated from the push rod 203a. Under the tensile action of the second spring 203c, the push rod 203a is pulled back, and the blocking protrusion 203b is fitted with the end of the shell 203d. At this time, the second spring 203c is still in a stretched state, tightly fitting one side of the blocking protrusion 203b to the end of the shell 203d, and the other side of the blocking protrusion 203b is flush with the surface of the injection molding convex plate.

[0059] When the injection molding concave plate 101, the injection molding middle plate 102 and the injection molding convex plate 201a are tightly fitted, the injection period begins. At this time, liquid injection plastic is injected. The liquid injection plastic enters the injection hole 201a-2 from the injection port 201c in turn, flows through the circulation groove 201a-3, and finally fits with the end of the blocking protrusion 203b. Since the injection pressure during the injection period is greater than the tensile force of the third spring 203f, the third spring 203f will be forced to compress a certain length, and the fixing ring 203e will move away from the stretching groove 201a-6, causing the shell 203d to displace synchronously, driving the blocking protrusion 203b at the end of the shell 203d to displace synchronously. At this time, the liquid injection plastic enters the injection molding chamber through the circulation groove 201a-3.

[0060] When the injection molding is completed, no more liquid injection material is injected into the interior, and the pressure holding period begins. At this time, the internal pressure is reduced relative to the injection period, the third spring 203f is stretched again, and the fixing ring 203e at the end of the shell 203d is re-fitted with the stretching groove 201a-6, and the blocking protrusion 203b fitted at the end of the shell 203d blocks the flow groove 201a-3 again, isolating the injection molding chamber from the flow groove 201a-3.

[0061] When the injection cavity is separated from the flow channel 201a-3, the cooling period is entered, the liquid injection material is solidified, and after reaching a certain hardness, the injection concave plate 101 and the injection middle plate 102 are separated from the injection convex plate 201a. Under the reset action of the first spring 202b, the auxiliary rod 202a is driven to synchronously drive the auxiliary connecting rod 202c, the sleeve ring 202d, the fixed connecting rod 202e and the synchronization pipe 202f. The synchronization pipe 202f will be attached to the bottom of the push rod 203a during displacement, so as to displace the push rod 203a. The displacement of the push rod 203a will make the second spring 203c stretch, and at the same time, the blocking convex block 203b will extend out of the push stop groove 201a-5, push the cooled injection product away from the mold surface, and finally separate from the mold, and the injection is completed once. At this time, the injection concave plate 101 and the injection middle plate 102 can be attached to the injection convex plate 201a again for the next injection.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application. They should be covered in the scope of the claims of the present application.
