Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, and more specifically, to a split-type magic tape injection mold. Background Art

[0002] Common magic tapes are used in combination with a hook surface and a loop surface sticking to each other. Generally, several hooks on the hook surface are injection-molded. Therefore, at this time, several curved holes need to be opened on the mold to cooperate with the curved hooks. Also, because the holes are curved, it is impossible to directly open the holes through a hole-opening device, because it is impossible to open a curved hole on a plate body. Therefore, the mold at this time needs to be formed by splicing several thin plates.

[0003] Common magic tapes are provided with several hooks on a plane. However, sometimes hooks need to be provided on a curved surface. At this time, the forming surface of the mold needs to be a curved surface with a corresponding radian, and it is difficult to align several thin plates of the existing magic tape injection mold. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides a split-type magic tape injection mold.

[0005] The utility model is realized as follows:

[0006] A split-type magic tape injection mold includes a mold, and the mold includes a mold core, a first fixing sleeve, and a second fixing sleeve. The mold core slides in the first fixing sleeve. The mold core is composed of several templates. A pair of connection holes are opened on one side of the mold core. Connection pins slide in the connection holes. A connection groove is opened at one end of the connection pin. Several first fixing grooves are opened on one side of the first fixing sleeve. A pin slides in a pair of the first fixing grooves. One end of the pin is connected to a fixing rod, and the fixing rod slides in the first fixing groove.

[0007] Further, the first fixing sleeve slides in the second fixing sleeve. Three groups of second fixing grooves are opened on one side of the second fixing sleeve. Rivets are connected between the second fixing grooves and the remaining three groups of the first fixing grooves.

[0008] The beneficial effect of adopting the above further scheme is that a pair of connection holes and a pair of connection pins are used to fix several templates together, and then the mold core is fixed in the first fixing sleeve by the connection pins and the connection grooves, so as to prevent several templates from spreading in the first fixing sleeve. The first fixing sleeve is fixed in the second fixing sleeve by rivets to prevent the connection pins from sliding out, thereby improving the accuracy of splicing between the templates.

[0009] Further, the height from both sides of the mold core to the center of the mold core gradually decreases, and the top of the mold core is a concave curved surface.

[0010] The beneficial effect of adopting the above further solution is that by controlling the shape and size of the template, the center of the assembled mold core can be made into a concave curved surface, enabling the hook hairs to be formed on the curved surface.

[0011] Further, several of the templates each include a core board and a partition board. The tops of the core board and the partition board are both arc-shaped. A pair of through holes are opened on one side of the core board and the partition board. The through holes of several of the templates form the connection hole.

[0012] Further, several curved hook-shaped mold cavities are opened on the top of the core board.

[0013] The beneficial effect of adopting the above further solution is that the curved hook-shaped mold cavities can be used to inject mold curved hook hairs.

[0014] Further, the mold core, the first fixing sleeve, and the second fixing sleeve are all made of metal.

[0015] Further, a first cavity matching the shape of the mold core is opened on the top of the first fixing sleeve, and a second cavity matching the shape of the first fixing sleeve is opened on the top of the second fixing sleeve.

[0016] The beneficial effect of the present utility model is as follows: An assembled magic tape injection mold obtained by the above design of the present utility model uses a pair of connection holes and a pair of connection pins to fix several templates together, and then uses the connection pins and connection grooves to fix the mold core in the first fixing sleeve, thereby preventing several templates from spreading in the first fixing sleeve. The first fixing sleeve is fixed in the second fixing sleeve by rivets to prevent the connection pins from slipping out, thereby improving the accuracy of splicing between the templates.
