Specific embodiment
The technical issues of to solve the utility model, the technical solution used and the technique effect reached are clearer,
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
A kind of injection mold is present embodiments provided, as shown in Figure 1, including front template, the preceding mould being arranged in front template
Benevolence 1, rear pattern plate, the rear cavity 2 being arranged in rear pattern plate, fixed plate 3 and pin 4, preceding diaphragm plate, rear pattern plate and fixed plate 3 are successively
It stacks, for forming the forming cavity of product 5, fixed plate 3 is used for the positioning and fixation of pin 4 for front template and rear pattern plate；Front template
On be provided with note cast gate, note cast gate is connected with forming cavity, and during injection molding, injected plastics material is entered by note cast gate in forming cavity, is passed through
Aftershaping is cooled down, product 5 is taken out by molding.
Specifically, the bottom surface of front cavity 1 is provided with location hole 11, for coordinating with the upper end of pin 4；Rear cavity 2 is set
It is equipped with the die cavity holes 21 through rear cavity 2；Fixed plate 3 is provided with connecting hole 31, the end of pin 4 in 21 correspondence position of die cavity holes
After sequentially passing through connecting hole 31 and die cavity holes 21, coordinate with location hole 11, between die cavity holes 21 and pin 4 formed product 5 into
Cavity.
In the present embodiment, lower end and the fixed plate 3 of pin 4 are fixed, after upper end sequentially passes through connecting hole 31 and die cavity holes 21
It stretches into the location hole 11 of front cavity 1 so that the both ends of pin 4 are fixed under the action of location hole 11 and connecting hole 31,
During injection molding, pin 4 is avoided to be deviated under the impact of injection pressure, so that position of the pin 4 in forming cavity is fixed,
And then prevent that molding product 5 is eccentric, it ensure that the concentricity of product 5, improve the stability of injection mold and the matter of product 5
Amount, beneficial to the long-term production of injection mold.
