Abstract
The utility model relates to a protection structure for eliminating damage caused by collision of an inclined ejection part and a straight ejection part to a female die, comprising a female die part, a male die part, an ejection part and a protection part, wherein the female die part is correspondingly arranged above the male die part; the ejection part is arranged at the side of the male die part and comprises a straight ejector rod as well as a straight ejector block, an upper ejector plate and a lower ejector plate which are fixed at the upper end of the straight ejector rod; the straight ejector block is contacted with an edge of a product and positioned at one side below the product; the straight ejector block penetrates through the upper ejector plate and is fixed on the lower ejector plate; the protection part comprises a reset rod and an elastic object positioned below the reset rod; the protection part is arranged at the side of the male part side and the other side of the product, and is opposite to the ejection part; the reset rod penetrates through the upper ejector plate and is contacted with the upper surface of the lower ejector plate; the lower ejector plate is provided with a hole below the reset rod; the elastic object is placed in the hole; and the length of the elastic object under natural state is greater than the height of the hole. The protection structure is stable and convenient to process and assemble.
Description
Technical field
The utility model relates to the injection mold field, and particularly a kind of oblique top is directly pushed up and bumped master mold protection structure.
Background technology
Oblique top is directly pushed up and is bumped master mold protection structure and have a variety ofly in the forming process of plasthetics, and as resetting-mechanism by force commonly used, directly release link is bumped the master mold part, travel switch elder generation horizontal reset etc.In the process of producing in batches, with these traditional protective device mechanisms, we see that through regular meeting straight top portion or oblique top partly have more and more serious burr, and master mold to death such as is collided at phenomenon.
The utility model content
Technical problem to be solved in the utility model provides a kind of oblique top and directly pushes up and bump master mold protection structure; the damage that this kind protection mechanism brought in the time of can protecting straight top or oblique top and master mold collision in producing kind; improve die life, reduce long-term production and the problems such as overlap that produce.
The technical scheme that its technical problem that solves the utility model adopts is: provide a kind of oblique top directly to push up and bump master mold protection structure, comprise master mold part, male model part, eject part, protect part; The corresponding male model part top that places of described master mold part; The described part that ejects is in male model part side; comprise straight push rod; be fixed on the straight jacking block of straight push rod upper end; last ejector retainner plate; following ejector retainner plate; described straight jacking block contacts with product edge and is positioned at its side-lower; described straight push rod passes ejector retainner plate and is fixed on down on the ejector retainner plate; it is characterized in that: described protection part comprises release link and places the elasticity thing of its below; described protection part is in male model part side; be positioned at ejection part and divide relative product opposite side; described release link is passed ejector retainner plate; contact with following ejector retainner plate surface; on the following ejector retainner plate; the release link below has the hole; described elasticity thing places in this hole, and the length under the described elasticity thing nature is greater than the height in hole.
Described elasticity thing is spring or excellent power glue.
Beneficial effect
The utility model can be in producing kind the damage that brings during with the master mold collision of the straight top of protection or oblique top, improve die life, minimizing long-term production and the problems such as overlap that produce.And the utility model Stability Analysis of Structures, process easy to assembly.
Description of drawings
Fig. 1 is the utility model schematic diagram under the mould matched moulds state.
Fig. 2 is the utility model schematic diagram under the mould die opening state.
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.
As shown in Figure 1, 2, a kind of oblique top is directly pushed up and is bumped master mold protection structure, comprises master mold part, male model part, ejects part, protects part; Described master mold part 1 corresponding male model part 4 tops that place; The described part that ejects is in the male model side; comprise straight push rod 3; be fixed on the straight jacking block 2 of straight push rod upper end; last ejector retainner plate 5; following ejector retainner plate 6; described straight jacking block 2 and product 9 EDGE CONTACT also are positioned at its side-lower; described straight push rod 3 passes ejector retainner plate 5 and is fixed on down on the ejector retainner plate 6; described protection part comprises release link 8 and places the elasticity thing 7 of its below; described protection part is in male model part 4 sides; be positioned at product 9 opposite sides; divide relative with ejection part; described release link 8 is passed ejector retainner plate 5; contact with following ejector retainner plate upper surface; on following ejector retainner plate; the release link below has the hole, and described elasticity thing 7 places in this hole, and the length under described elasticity thing 7 natures is greater than the height in hole.
Described elasticity thing 7 is spring or excellent power glue
Concrete motion process of the present utility model is as follows:
In the injection moulding process, the elasticity thing 7 of protection part is in preloading condition, after product 9 moulding, the mould die sinking, male model part 4 parts are opened, and elasticity thing 7 pressure of protection part discharge, therefore release link 8 moves upward, arrive the spacing distance of protection, male model part 4 is opened fully at this moment, ejects product by ejecting part; During the mould matched moulds, owing to there is the elasticity thing 7 of below to support, release link 8 resets to be slower than and ejects part, ejects part like this and just can directly not bump master mold part 1, all plays a protective role to ejecting part and master mold part 1.
Claims (2)
1. an oblique top is directly pushed up and is bumped master mold protection structure, comprises master mold part, male model part, ejects part, protects part; Corresponding male model part (4) top that places of described master mold part (1); The described part that ejects is in male model part side; comprise straight push rod (3); be fixed on the straight jacking block (2) of straight push rod upper end; last ejector retainner plate (5); following ejector retainner plate (6); described straight jacking block (2) and product (9) EDGE CONTACT also are positioned at its side-lower; described straight push rod (3) passes ejector retainner plate (5) and is fixed on down on the ejector retainner plate (6); it is characterized in that: described protection part comprises release link (8) and places the elasticity thing (7) of its below; described protection part is in male model part (4) side; be positioned at product (9) opposite side; divide relative with ejection part; described release link (8) is passed ejector retainner plate (5); contact with following ejector retainner plate upper surface; on following ejector retainner plate; the release link below has the hole, and described elasticity thing (7) places in this hole, and the length under described elasticity thing (7) nature is greater than the height in hole.
