Description

Technical Field

[0001] The present invention specifically relates to an assembly mold for a special-shaped intake pipe. Background Art

[0002] For products such as special-shaped intake pipes, due to the particularity of the product structure, it is impossible to use a conventional compression mold for compression molding. Generally, in the production process of a compression mold, effective demolding cannot be achieved, resulting in waste of man-hours. At the same time, the product qualification rate is low, and cracks and defects are likely to occur, causing low customer satisfaction. Adopting an injection design mold structure can effectively solve this type of problem. However, a conventional injection molding mold generally has an upper template, a runner middle template, a heat insulation plate, and a runner lower template, with a relatively large number of structures. The mold processing cost is high, the processing cycle is long, it is not convenient to simplify the structure, and for the integral lower template, it is also inconvenient for later maintenance. Therefore, we propose an assembly mold for a special-shaped intake pipe. Summary of the Invention

[0003] The purpose of the present invention is to provide an assembly mold for a special-shaped intake pipe to solve the problems raised in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An assembly mold for a special-shaped intake pipe, comprising:

[0006] A middle mold lifting plate is arranged between the upper template and the lower template to support the inner wall of the intake pipe, and guide columns for guiding the middle mold lifting plate are arranged at the edge of the upper surface of the lower template;

[0007] Wherein, a runner is opened at the center of the upper surface of the lower template, and a lower mold cavity for forming the intake pipe is provided at the end of the runner. An insert for shaping the outer wall of the intake pipe is provided at the edge of the lower mold cavity.

[0008] Preferably, a plurality of inserts are provided, and the inserts are detachably connected to the lower template.

[0009] Preferably, the middle mold lifting plate includes a first lifting plate, a second lifting plate, a first mold core, and a second mold core structure. The first lifting plate is detachably connected to both ends of the second lifting plate. A second mold core structure is slidably connected to one side wall of the first lifting plate, and the second mold core structure cooperates with the first mold core on one side wall of the second lifting plate to shape the inner wall of the intake pipe.

[0010] Preferably, the second die core structure includes a connecting plate, a third lifting plate and a second die core. The connecting plate is slidably connected to one side wall of the first lifting plate, and a third lifting plate arranged side by side with the second lifting plate is fixed to one side wall of the connecting plate. The second die core is fixed to one side wall of the third lifting plate, and the second die core corresponds to the end of the first die core.

[0011] Preferably, a chute is formed in one side wall of the first lifting plate, and the connecting plate and the first lifting plate are slidably matched through the chute.

[0012] Preferably, positioning grooves corresponding to the middle die lifting plate are formed in the lower template, and the guide posts are fixed inside the positioning grooves.

[0015] Preferably, there are two lower die cavities.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By providing a lower template, an upper template and a middle die lifting plate, the present application avoids the need for a runner middle template and a heat insulation plate in the traditional special-shaped intake pipe die. The device can be made with only three plates, simplifying the die structure. And only a runner is formed on the upper surface of the lower template, so that the special-shaped intake pipe can be processed, greatly saving the manufacturing cost and processing cycle of the die, improving the material utilization rate. And through the design of the insert, the manufacturing difficulty of the die is also reduced, and the parts can be processed separately, which is also beneficial to replacement and maintenance in the later stage.

[0028] Preferably, a plurality of inserts 7 are provided, and the inserts 7 are detachably connected to the lower template 1, facilitating later disassembly, maintenance and replacement, and improving the convenience of maintenance.

[0029] Preferably, the middle mold lifting plate 4 includes a first lifting plate 401, a second lifting plate 402, a first mold core 403 and a second mold core structure. The two ends of the second lifting plate 402 are detachably connected to the first lifting plate 401. A second mold core structure is slidably connected to one side wall of the first lifting plate 401, and the second mold core structure cooperates with the first mold core 403 on one side wall of the second lifting plate 402 to shape the inner wall of the intake pipe, facilitating better shaping of the inner wall of the special-shaped intake pipe. After shaping, the first mold core 403 and the second mold core 406 are withdrawn from the inside of the special-shaped intake pipe to facilitate demolding.

[0030] Preferably, the second core structure includes a connecting plate 404, a third lifting plate 405 and a second core 406. The connecting plate 404 is slidably connected to one side wall of the first lifting plate 401, and a third lifting plate 405 arranged side by side with the second lifting plate 402 is fixed to one side wall of the connecting plate 404. The second core 406 is fixed to one side wall of the third lifting plate 405, and the second core 406 corresponds to the end of the first core 403, which is convenient for better withdrawing the second core 406 from the special-shaped air inlet pipe to facilitate demolding.

[0031] Preferably, a chute is provided on one side wall of the first lifting plate 401, and the connecting plate 404 and the first lifting plate 401 are slidably matched through the chute, which is convenient for the first lifting plate 401 to drive the second core 406 to move linearly better.
