Abstract

The utility model discloses a clamping fixture for embedding and ejecting inserts of a mold with two cavities, and belongs to the field of plastic moulds. The fixture comprises a push plate, two groups of opposite eject pins are fixed at the position where two ends of the push plate is corresponding to cavities of a mold, each group of eject pins consists of four eject pins, and any two eject pins of each group of eject pins are sleeved with linear springs. A loading plate is arranged parallel with the push plate, the groups of eject pins penetrate through the loading plate, and the linear springs are pressed between the groups of eject pins and the loading plate. A clamping body is arranged on one sides of the groups of eject pins extending out of the loading plate in sleeved mode, and fixed on the loading plate. The top of the clamping body is sunk to form two insert grooves, and the bottoms of the insert grooves abut against the eject pins in movable connection mode. A steel ball guide sleeve fixedly penetrates at the position of the push plate corresponding to a mold locating hole, a guide pillar penetrates through the steel ball guide sleeve and the loading plate and is fixed with the loading plate, and one end of the steel ball guide sleeve is limited through a fixed washer. A limiting pillar is arranged between the push plate and the loading plate. The fixture is capable of accomplishing the assembly of the inserts of the mold with two cavities at a time and improving the production efficiency, simultaneously no potential safety hazard exists.

Description

Two caves are hidden and are penetrated inserts clamping anchor clamps

Technical field

The utility model relates to the plastic mould field, specifically is a kind ofly to be used for hiding of two cave moulds and to penetrate inserts clamping anchor clamps.

Background technology

In plastic mould injection mo(u)lding production process, for mould with inserts, all need again inserts to be packed in process of production mold cavity, during production, generally put on one's gloves by the workman, with the hand corresponding die cavity of mould of directly inserts being packed into, and also need operate by the son of taking the photograph of non-five metals for the mould of some deep holes; And a cover plastic mould generally has a plurality of symmetrically arranged inserts, and therefore, there are the following problems in the production process: on the one hand, the mould of high temperature causes injury to the people easily, simultaneously, and also can the mold damage mold cavity surface when staff irriate shrinks; On the other hand, the assembling of inserts need expend a large amount of man-hours, and production efficiency is low.

Summary of the invention

At the problem that exists in the production process, the utility model provides a kind of two caves to hide and penetrates inserts clamping anchor clamps, to enhance productivity and security.

For achieving the above object, the technical solution adopted in the utility model is as follows:

A kind of two caves are hidden and are penetrated inserts clamping anchor clamps, comprise a rectangle slurcam, and the mould hole position place of corresponding mould is fixed with the two opposite groups thimble at the slurcam two ends, and every group is four, is with Hookean spring on any therein two thimbles; The parallel loading plate that is provided with slurcam, the thimble group runs through this loading plate, and Hookean spring is pressed between slurcam and the loading plate; The thimble group is stretched out a side of loading plate and is arranged with the clamping main body, and the clamping main body is fixed on loads on the plate, and its top depression becomes two inserts draw-in grooves, this draw-in groove bottom and the movable butt of thimble; The position of corresponding mould locating hole also fixedly is equipped with the steel ball guide pin bushing on slurcam, have guide pillar to run through steel ball guide pin bushing and loading plate, and fix with loading plate, and guide pin bushing one end comes spacing by setting-up piece; Between slurcam and loading plate, also be provided with limited post.

The beneficial effects of the utility model are: adopt above-mentioned hiding behind the formula anchor clamps, can once finish all inserts assemblings, greatly improved production efficiency, simultaneously, also need not workman's hand and stretch into mold cavity, no potential safety hazard.

Description of drawings

Fig. 1 is that the structural representation that penetrates inserts clamping anchor clamps is hidden in two caves.

The specific embodiment

Below in conjunction with concrete embodiment the utility model is described further:

With reference to figure 1, a kind of two caves are hidden and are penetrated inserts clamping anchor clamps, comprise a rectangle slurcam 1, and the mould hole position place of corresponding mould is fixed with 2, two groups of thimbles of two opposite groups thimble, 2 phase phasic differences, 180 degree at slurcam 1 two ends; Every group of thimble 2 is four, is Eight characters shape and is symmetrically distributed, and is with Hookean spring 3 on any therein two thimbles 2; With the slurcam 1 parallel loading plate 4 that is provided with, the thimble group runs through this loading plate 4, and Hookean spring 3 is pressed between slurcam 1 and the loading plate 4; The thimble group is stretched out a side of loading plate 4 and is arranged with clamping main body 5, and clamping main body 5 is fixed on loads on the plate 4, and its top depression becomes two inserts draw-in grooves, this draw-in groove bottom and thimble 2 movable butts; The position of corresponding mould locating hole also fixedly is equipped with steel ball guide pin bushing 6 on slurcam 1, there is guide pillar 7 to run through steel ball guide pin bushing 6 and loading plate 4, and it is fixing with loading plate 4 by snap ring 8, and guide pin bushing 6 one ends are fixed with pad 9 by screw, spacing by pad 9, with slurcam 1 with load plate 4 and be assembled together versatilely; Loading plate 4 one sides between slurcam 1 and loading plate 4 also are provided with limited post 10.

During the clamping operation, guide pillar 7 is connected to the mould locating hole, gives slurcam 1 application of force, and it is slided along guide pillar 7, and at this moment, the thimble group on the slurcam 1 is clamping main body 5 slips relatively also, and the inserts that is loaded in the inserts draw-in groove is ejected; After finishing clamping, because of Hookean spring 3 from restoring force, make slurcam 1 return initial position.

Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of being done according to the described scheme of the utility model patent claim change or modify, is included in the utility model patent claim.

Claims
