Abstract
The utility model discloses a mould convenient for clearing away wastes in a runner, relating to the technical field of moulds. The utility model aims at solving the problem that the production cost of products is increased as the traditional mould is complex in structure and operation in order to clear away wastes. The mould comprises at least two laminated formworks; a cavity is formed between the adjacent formworks; waste pull-out structures are arranged on parting surfaces of the formworks and are respectively communicated with vertical runners and the cavities in the formworks. The waste pull-out structures are blind holes close to the cavities; and threads are machined inside the blind holes. The mould is particularly suitable for clearing away wastes in the runner of the plastic mould.
Description
Technical field
The utility model relates to technical field of mold, relates in particular to a kind of mould of being convenient to remove plastic cement waste material in the mold runner.
Background technology
Injecting molding die in the rubber mold is that the sizing material that will preheat into mecystasis injects the mould first cure through the running gate system of injection mould.Be applicable to and make large-scale, heavy wall, thin-walled, complex-shaped rubber.In producing automobile during parts such as air filter, injection plasticity sizing material behind upper die and lower die and the core matched moulds, because the thickness of patrix template is bigger, correspondingly the vertical length of its inner runner that is provided with is elongated, after the formed product, vertically residual waste material is also longer in the runner, not only cause the waste of plastic material, has also increased the difficulty that the waste material bearded needle is pulled out waste material.Patent No. ZL 200820048532.2, Granted publication CN 201240014Y, China's utility model patent name is called a kind of three template dies, it embeds between upper die and lower die and inserts, the waste material bearded needle of patrix passes the through hole on inserting, inserting embeds the inserting slot of counterdie and covers on the runner, and that inserts is arranged so that runner place corresponding thickness reduces in the template, is easy to the waste material bearded needle and pulls out waste material.But the mode of this removing waste material makes the structure of mould be tending towards complicated, and complex operation has increased production cost of products.
Summary of the invention
Cause structure to be tending towards complicated at existing mould for removing waste material, complex operation has increased the deficiency of production cost.The purpose of this utility model provides a kind of convenient mould of removing waste material in the runner simple in structure, easy and simple to handle.
The technical solution adopted for the present invention to solve the technical problems is: comprise at least two stacked templates, constitute die cavity between the described adjacent forms, the die joint of described template is provided with the waste material drawer structure, and described waste material drawer structure communicates with vertical runner and described die cavity in the template respectively.
Further, described waste material drawer structure is the blind hole near described die cavity, is processed with internal thread in the described blind hole.
Further, described waste material drawer structure is the blind hole near described die cavity, is provided with in the described blind hole and is processed with externally threaded boss, and the height of described boss is less than or equal to the degree of depth of described blind hole.
The beneficial effect of this patent is: utilize the waste material drawer structure that is provided with on the die joint of plastic mould, melten gel forms rubber scrap behind the sulfidization molding within it, be formed with on the rubber scrap with the waste material drawer structure in the screw thread that matches, when dividing mould, because the interlocking of screw thread, one end of rubber scrap still is fixed in the waste material drawer structure, make that the rubber scrap in the patrix is drawn out, thereby has played the purpose of removing in the mould rubber scrap in the vertical runner.The utility model is simple in structure, processes simple and easyly, easy to operate, can remove the waste material in the runner fast, has avoided for this reason and the structural design of the complexity that produces, thereby has reduced production cost of products.

The vertical runner of 1-patrix 2-counterdie 3-core 4-
5-waste material drawer structure 6-die cavity
The specific embodiment
Below will describe technology contents of the present utility model and feature in detail by cited embodiment in conjunction with the accompanying drawings.
Embodiment 1: in conjunction with Fig. 1 to Fig. 3 a kind of mould of being convenient to remove waste material in the runner of the present utility model is described, when producing in the automobile parts such as air filter, patrix 1, injection plasticity sizing material behind counterdie 2 and core 3 matched moulds, the plasticity sizing material enters in the die cavity 6 by runner, because goods are hollow tubular, radius is big and cause in the patrix 1 that vertically runner 4 is longer, waste material drawer structure 5 communicates with die cavity 6 and vertical runner 4 respectively, the waste material drawer structure 5 that close die cavity 6 is provided with is the blind hole on the die joint of counterdie 2, the sidewall of blind hole is processed with internal thread, when the plasticity sizing material enters die cavity 6 by vertical runner 4, the sub-fraction sizing material flows into and is full of the blind hole of the waste material drawer structure 5 of die cavity 6 porch, melten gel forms rubber scrap behind the sulfidization molding within it, be formed with on the rubber scrap with blind hole in the screw thread that matches, when dividing mould, because the interlocking of screw thread, one end of rubber scrap still is fixed in the blind hole, make the rubber scrap in the patrix 1 to be drawn out, thereby played the purpose of removing in the mould rubber scrap in the vertical runner 4.
Embodiment 2: in conjunction with Fig. 4 present embodiment is described, as different from Example 1, is provided with externally threaded boss in the blind hole, leave the space between the sidewall of boss and blind hole, so that the filling of melten gel.In addition, the cross section of blind hole also can be trapezoidal to the opening flaring, so that the pulling out of rubber scrap.
Those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
