[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] As attached Figures 1-5 The injection mold for the positioning and clamping terminal shown can be fitted together with the second mold body 4 and the first mold body 3 through the molding component set on the support base 1. At the same time, the injection head 11 can be located at one end of the molding cavity 5, which facilitates the delivery of raw materials to the molding cavity 5 through the injection head 11 during injection. When the traction rod 6 moves downward, the slider 7 will slide in the slide groove 9 due to the traction force of the traction rod 6, and the inner liner 13 will be inserted into the molding cavity 5, which facilitates the molding of raw materials. When demolding, the output end of the electric push rod 12 drives the pressure plate 2 to move the second mold body 4 upward, which causes the slider 7 to move the inner liner 13 and disengage the inner liner 13 from the molding cavity 5. This makes the molded workpiece lose its limit in the molding cavity 5, which is easy for the staff to pick up the material and ensures the quality of injection molding. The specific structural settings of the component are as follows.

[0024] The molding assembly includes a pressure plate 2 disposed on the top of the support base 1, a first mold body 3 is snapped into the top of the support base 1, a second mold body 4 is snapped into the bottom of the pressure plate 2, and molding cavities 5 are opened on the top surface of the first mold body 3 and the bottom surface of the second mold body 4.

[0025] A plurality of sliding grooves 9 are formed in the support base 1, and each sliding groove 9 is located at one end of the first mold body 3. A plurality of sliding blocks 7 are slidably connected in the sliding grooves 9. A plurality of traction rods 6 are arranged on the two sides of the second mold body 4, and each traction rod 6 is clamped with the pressing plate 2. The plurality of traction rods 6 are arranged obliquely downward. A plurality of through holes 8 are formed in the plurality of sliding blocks 7, and each traction rod 6 extends into the corresponding through hole 8. The through hole 8 is slidably connected with the traction rod 6. One end of the plurality of sliding blocks 7 is threadedly connected with the through hole 8, and the through hole 8 extends into the forming cavity 5.

[0026] A mounting hole 10 is formed in the pressing plate 2. An injection head 11 is embedded in the mounting hole 10. The injection head 11 is located at one end of the forming cavity 5. An electric push rod 12 is inserted into the top four corners of the support base 1, and the output end of each electric push rod 12 extends to the bottom of the pressing plate 2.

[0027] According to the above structure, when the terminal is injection molded, the output end of the electric push rod 12 drives the pressing plate 2, the second mold body 4, the injection head 11 and the traction rod 6 to displace downward, and the second mold body 4 and the first mold body 3 can be attached together. At the same time, the injection head 11 can be located at one end of the forming cavity 5, so that the raw materials can be easily conveyed into the forming cavity 5 through the injection head 11 during injection molding;

[0028] At the same time, when the traction rod 6 displaces downward, the traction force of the sliding block 7 during displacement of the traction rod 6 will slide in the sliding groove 9, and the inner lining cylinder 13 will be inserted into the forming cavity 5, so that the raw materials can be easily molded. When demolding subsequently, the output end of the electric push rod 12 drives the pressing plate 2 to displace the second mold body 4 upward, so that the sliding block 7 drives the inner lining cylinder 13 to displace and makes the inner lining cylinder 13 disengage from the forming cavity 5, so that the molded workpiece loses the limit in the forming cavity 5, which is easy for the worker to take the material and ensures the quality of injection molding.

[0029] Different from the prior art, the application discloses an injection mold for positioning and clamping terminals. The second mold body 4 and the first mold body 3 can be attached together, and the injection head 11 can be located at one end of the forming cavity 5, so that the raw materials can be easily conveyed into the forming cavity 5 through the injection head 11 during injection molding. At the same time, when the traction rod 6 displaces downward, the traction force of the sliding block 7 during displacement of the traction rod 6 will slide in the sliding groove 9, and the inner lining cylinder 13 will be inserted into the forming cavity 5, so that the raw materials can be easily molded. When demolding subsequently, the output end of the electric push rod 12 drives the pressing plate 2 to displace the second mold body 4 upward, so that the sliding block 7 drives the inner lining cylinder 13 to displace and makes the inner lining cylinder 13 disengage from the forming cavity 5, so that the molded workpiece loses the limit in the forming cavity 5, which is easy for the worker to take the material and ensures the quality of injection molding.

[0030] The above are only preferred embodiments of the present application, and are not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
