Abstract

The utility model relates to the technical field of cutting fixtures and particularly relates to a double-gate cutting fixture. The double-gate cutting fixture is characterized by consisting of an upper template, a lower template, upper die cutters, lower die cutters, a fixed plate and limiting blocks, wherein the upper template and the lower template are overlapped and are fixed on a pneumatic punching machine and are linked with the pneumatic punching machine; the limiting blocks are symmetrically arranged at the left end and the right end of the lower surface of the lower template; the fixed plate is locked to the lower surface of the lower template through the limiting blocks; two groups of upper die cutters are symmetrically arranged on the lower surface of the lower template; two groups of lower die cutters are correspondingly arranged on the upper surface of the fixed plate; each group of upper die cutters is matched with the lower die cutters. According to the fixture, the yield for corresponding production is greatly increased, the convenience for taking is realized and the efficiency is increased; by applying the double-gate cutting fixture, the labor cost can be reduced, the workload finished by four workers originally can be finished by one worker and the time is saved; compared with a manual cutting mode, a machine cutting mode has the advantages that the defect rate is reduced and the production value is increased.

Description

A kind of double cast gate cutting tool

[technical field]

The utility model relates to cutting tool technical field, specifically a kind of double cast gate cutting tool.

[background technology]

Having a hidden danger for producing precise injection molding production industry, owing to will certainly causing cast gate and product to be connected together after injecting products moulding, particularly double cast gate product, also there is some problems in cutting.Fracture the by hand words of product and cast gate of personnel more can increase bad ratio, cause cost to rise, the waste of manpower and materials; Still designed a set of double cast gate blanking jig for this reason, carry out this cover tool cutting, two cast gates can excise simultaneously, defective products ratio in also avoiding producing makes to produce and can carry out convenient and efficiently simultaneously.

Realize double cast gate cutting, the not only problem of precision of Gonna breakthrough deformation of products technically, on product orientation, difficulty also can be larger in addition, we adopt high-accuracy processing and high-accuracy navigation system, the repetitive positioning accuracy of product is controlled in 0.005mm, guarantees that like this product excision cast gate tolerance is afterwards at 0.01mm.

[summary of the invention]

The purpose of this utility model is to overcome the defect that prior art exists, and a kind of double cast gate cutting tool is provided.

For achieving the above object, design a kind of double cast gate cutting tool, it is characterized in that: described cutting tool is by cope match-plate pattern, lower bolster, patrix cutter, lower die cutter, fixed head, limited block composition, described cope match-plate pattern and lower bolster superpose and are fixed on pneumatic punching machine, link with pneumatic punching machine, the two ends, lower surface left and right of described lower bolster are arranged with limited block, fixed head is locked at the lower surface of lower bolster by described limited block, the lower surface of described lower bolster is arranged with two groups of patrix cuttves, the upper surface correspondence of described fixed head is provided with two groups of lower die cutters, every group of patrix cutter and lower die cutter are suitable.Patrix cutter coordinates pneumatic little punch press well to complete blank work with lower die cutter, not only save time but also laborsaving, has reduced greatly personnel cost and Material Cost, has improved again the output of product.

On two groups of lower die cutters of described fixed head upper surface, be fixed with product to be cut, the right and left of described product to be cut is spacing fixing by limited block, does not hurt product while ensureing blank.Product can complete and the cut-out of cast gate rapidly like this, ensures that quantity and quality takes into account simultaneously, has improved production efficiency.

Described fixed head is provided with infrared location induction installation, realizes Precision Machining.

Described fixed head is provided with the resetting structure of being made up of high-molecular organic material, and the precision of described resetting structure is 0.005mm, guarantees that one of structure makes peace permanent.

This cover tool has following advantage:

One, the raising of production capacity: can improve greatly production capacity when corresponding production after this cover tool completes, fetch conveniently, efficiency improves;

Two, saving of time and fraction defective reduce: this cover tool can reduce personnel cost after using, 4 people's workload originally, and a present people just can complete, and saves time.Machine blank reduces fraction defective than artificial blank far away, has increased the output value.

Fig. 2 is the three-dimensional reference diagram of the utility model cutting tool;

In figure 1, cope match-plate pattern; 2, lower bolster; 3, fixed head; 4, patrix cutter; 5, lower die cutter; 6, limited block.

[detailed description of the invention]

Now by reference to the accompanying drawings and embodiment the technical solution of the utility model is further elaborated, believe it is clearly for a person skilled in the art.

Double cast gate cutting tool as depicted in figs. 1 and 2, is made up of cope match-plate pattern 1, lower bolster 2, patrix cutter 4, lower die cutter 5, fixed head 3, limited block 6, specifically:

First, cope match-plate pattern 1 and lower bolster 2 are superposeed, be connected and fixed at top and the pneumatic punching machine of cope match-plate pattern 1, link with pneumatic punching machine;

Secondly, at the lower surface of lower bolster 2 with two groups of patrix cuttves 4 of the symmetrical installation of guide center, with the symmetrical installation of guide center and two groups of two groups of lower die cutters 5 that patrix cutter 4 is corresponding, make every group of patrix cutter 4 and lower die cutter 5 suitable at the upper surface of fixed head 3;

Then, the symmetrical mounting limit piece in the two ends, lower surface left and right of lower bolster 2, fixed head is locked at the lower surface of lower bolster by described limited block; Between fixed head upper surface, limited block, fix product to be cut.

Finally, can be on fixed head 3 installation infrared location induction installation and the resetting structure made by high-molecular organic material, locate product to be cut, the precision of resetting structure is 0.005mm.

Product to be cut is fixed on two groups of lower die cutters of fixed head upper surface, the both sides of product to be cut are spacing fixing by limited block, and the top of product to be cut is spacing fixing by cope match-plate pattern and lower bolster; Cope match-plate pattern and lower bolster superpose and are fixed on pneumatic punching machine, pneumatic punching machine drives cope match-plate pattern, lower bolster and two groups of patrix cuttves to pump, due to every group of patrix cutter and lower die cutter suitable, and every group of patrix cutter one group cast gate corresponding to lower die cutter, when two groups of patrix cuttves pump, and complete rapidly the cut-out of product and cast gate while offseting with lower die cutter.
