Abstract

The utility model relates to a submarine slide block type injection structure. The structure comprises a valve type hot sprue bushing (1), a cavity insert (2), a slide block (3) and a core insert (4), wherein a groove (7) is formed at the top of the slide block (3), a culvert (8) is formed closely below the groove (7) and matched with a stub bar (5) of a plastic product to be formed (6), the lower half part of the valve type hot sprue bushing (1) is embedded in the cavity insert (2), the position of a sprue bushing of the valve type hot sprue bushing (1) is corresponding to that of the stub bar (5), the cavity insert (2) and the core insert (4) are vertically matched with each other, the upper surface of the slide block (3) is matched with the cavity insert (2), and the left lower part of the slide block (3) is matched with the core insert (4). The utility model can solve the problem in the prior art that the appearance of a formed product is defective due to injection.

Description

A kind of slide block submarine advances plastic structure

Technical field

The utility model belongs to submarine and advances the glue technical field, particularly relates to a kind of slide block submarine and advances plastic structure.

Background technology

Therefore in the forming process of plasthetics, usually need adopt the into mode of glue of hiding, often can use ox horn and advance glue, the point type into glue of hiding.And these traditional hide into that the glue mode produces defectives such as cold burden, gas trace through regular meeting at Surface Appearance in the process of plastic rubber shaping.And its pressure loss is bigger, and pressurize is insufficient in forming process.Therefore generally only be fit to the moulding of the less small sized product of glue mode glue mouth into, and can not apply in the large scale plastic product.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of slide block submarine and advances plastic structure, to solve the problem of advancing the moulding product open defect that glue causes in the prior art.

The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of slide block submarine to advance plastic structure, comprise valve formula heat filling mouth, mother module core, slide block and male model benevolence, the top of described slide block is fluted, and then the below is the culvert that agrees with mutually with the stub bar of plastic products to be formed, described valve formula heat is irritated mouth the latter half and is embedded in the mother module core, the corresponding stub bar in its Guan Zui position.

Described mother module core and male model benevolence are the structure of agreeing with up and down, described slide block upper surface and mother module core agrees with, lower left and male model benevolence are agreed with.

Beneficial effect

Moulding problems such as the utility model has well solved cold burden, gas trace, the pressure loss is big, pressurize is insufficient do not influence product appearance, and it is convenient that Jiao Kou removes, flexible transformation, operate simple and easy, low cost of manufacture; Make and to hide into that the glue mode can apply in the middle of the injection mo(u)lding of large-scale plastic products such as automobile plastic goods well.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

As shown in Figure 1, a kind of slide block submarine advances plastic structure, comprise valve formula heat filling mouth 1, mother module core 2, slide block 3 and male model benevolence 4, the top of described slide block 3 fluted 7, and then the below is the culvert 8 that agrees with mutually with the stub bar 5 of plastic products 6 to be formed, described valve formula heat is irritated mouth 1 the latter half and is embedded in the mother module core 2, the corresponding stub bar 5 in its Guan Zui position.

The structure of described mother module core 2 and male model benevolence 4 for agreeing with up and down, described slide block 3 upper surfaces and mother module core 2 agrees with, lower left and male model benevolence 4 are agreed with.

As shown in Figure 1, heat is irritated mouth 1 and is directly advanced glue to slide block 3 by mother module core 2, and plastics advance glue by the culvert on the slide block 38; As shown in Figure 2, heat is irritated mouth 1 during the mould die sinking, mother module core 2 breaks away from male model benevolence 4, and slide block 3 moves right stub bar 5 is deviate from fully simultaneously.

Claims

1. a slide block submarine advances plastic structure, comprise valve formula heat filling mouth (1), mother module core (2), slide block (3) and male model benevolence (4), it is characterized in that: the top of described slide block (3) fluted (7), and then the below is the culvert (8) that agrees with mutually with the stub bar (5) of plastic products to be formed (6), described valve formula heat is irritated mouth (1) the latter half and is embedded in the mother module core (2), the corresponding stub bar (5) in its Guan Zui position.

2. a kind of slide block submarine according to claim 1 advances plastic structure, it is characterized in that: described mother module core (2) and male model benevolence (4) are the structure of agreeing with up and down, and described slide block (3) upper surface and mother module core (2) agree with, lower left and male model benevolence (4) are agreed with.
