Description

A mold that facilitates the disassembly and assembly of exhaust inserts

technical field

The utility model relates to the technical field of moulds, in particular to a mould, which facilitates the disassembly and assembly of exhaust inserts.

Background technique

With the rapid development of the manufacturing industry, molds are widely used in actual production, and molds often generate certain pressure in the cavity during the injection molding process, so that the cavity is affected by the injection pressure and generates high-temperature and high-pressure gas. , resulting in insufficient injection molding in the cavity and a high scrap rate of the product.

Existing molds are often equipped with exhaust inserts to connect the cavity and the outside world, so that the air pressure in the cavity tends to be stable, and it is not easy to generate high-temperature and high-pressure gas. Although the exhaust insert is used to solve the problem of insufficient injection molding, during the injection molding process, part of the injection molding raw materials enter the gap between the exhaust insert and the cavity, which is easy to cause blockage, and after a while Needs to be cleaned. When the exhaust insert needs to be cleaned or replaced, first remove the whole mold from the frame; then remove the bolts to separate the mold core from the template, and then combine the exhaust insert and the insert base between the two Remove it, and then separate the exhaust insert from the insert base, so as to complete the cleaning or replacement of the exhaust insert.

It can be seen from the above that, in the process of cleaning or replacing the exhaust insert, it is necessary to disassemble the mold as a whole relative to the machine frame, and it is necessary to disassemble each part of the mold from each other. It consumes a lot of manpower and material resources, wastes valuable production time, and greatly reduces production efficiency.

detailed description

In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer, the utility model will be further described in detail below in combination with the embodiments and accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The utility model provides a mold for convenient disassembly and assembly of exhaust inserts, as shown in Figures 1 to 4, including mold core 1, exhaust insert 2, insert base 3 and first template 4, exhaust insert Part 2 is set on the insert base 3, and the insert base 3 is set on the mold core 1, and the mold core 1 is set on the first template 4; it also includes a push rod 5, a push rod seat 6 and a cam 7, and the first template 4 is provided with a The guide hole 41 for the axial movement of the ejector rod 5; one end of the ejector rod 5 is connected with the insert base 3, and the other end of the ejector rod 5 is connected with the ejector rod seat 5; the cam abuts with the insert base 3 to drive The push rod 5 moves axially under the action of the push rod. It also includes a transmission rod 8, and the cam is fixedly connected with the end of the transmission rod 8. When the exhaust insert 2 needs to be cleaned, the transmission rod 8 drives the cam 7 to rotate, and the cam 7 pushes out the exhaust insert 2 along the axial direction of the ejector rod 5, and the exhaust insert 2 can be taken out for cleaning; the exhaust insert 2 is installed 2, eject the insert base 3, install the exhaust insert 2 on the insert base 3, and then turn the cam 7 to install the exhaust insert 2 into the mold core 1. Compared with the prior art, when the exhaust insert 2 needs to be cleaned, it is not necessary to disassemble the die core 1 template, and the exhaust insert 2 can be disassembled by adopting the matching structure of the cam 7 and the ejector pin 5 . In addition, because the cam mechanism has a relatively compact structure and high reliability, it will not be dislocated from the ejector rod seat 6; the energy consumption of the cam is relatively small, and the cam structure can obtain a smooth movement, which can quickly eject the exhaust insert 2 And the effect of quick installation in place.

In this embodiment, the ejector rod seat 6 is provided with a cam accommodation space 61 , the cam accommodation space 61 is a cam groove or a cam hole, and the cam 7 is disposed in the cam accommodation space 61 . The cam 7 is embedded in the cam accommodation space 61 of the ejector seat 6, so that the cooperation between the cam 7 and the ejector seat 6 is more stable, the error of the offset of the cam 7 relative to the ejector seat 6 is reduced, and the mutual interaction is more effective. power transfer between.

In this embodiment, it also includes a second template 9, a third template 10 and a transmission rod seat 11, the transmission rod seat 11 is arranged between the second template 9 and the third template 10, and the transmission rod seat 11 is provided with a transmission rod 8 A slot or hole passing axially. The transmission rod 8 is generally arranged horizontally, because the transmission rod 8 is fixedly connected with the cam 7, and when the transmission rod 8 deviates, the cam 7 will also deviate accordingly, so the transmission rod 8 also needs to be set relatively stably. The transmission rod seat 11 is provided with a hole for the transmission rod 8 to pass through in the axial direction or a groove outside the transmission rod seat 11. In the axial direction of the transmission rod 8, the transmission rod 8 is more horizontal and further makes the cam 7 relatively It is more stable at the mandrel seat 6.

In this embodiment, a groove 611 extends from the cam accommodating space 61 to the side away from the exhaust insert 2 , and the end of the ejector pin seat 6 away from the ejector pin 5 protrudes from the third template 10 . After the cam is designed, its displacement over time is definite, which provides a guarantee for the exhaust insert 2 to be pushed out of the mold core 1 in one step and installed into the mold core 1 in one step. The cam groove or cam hole 61 is provided with a groove 611 along the side away from the exhaust insert 2, and the ejector rod seat 6 protrudes from the third template 10, which is to use when the ejection stroke of the exhaust insert 2 is not enough. The groove on the ejector pin seat 6 assists the exhaust insert 2 to be pushed out of the mold core 1 smoothly, providing another kind of guarantee.

In this embodiment, both ends of the ejector rod 5 are provided with annular grooves 51, and the side of the insert base 3 away from the exhaust insert 2 and the end of the ejector rod seat 6 close to the ejector rod 5 are provided with annular grooves 51. The chute 31,62 that the groove 51 cooperates. The force is mainly transmitted between the ejector seat 6, the ejector bar 5 and the insert base 3. When installing or disassembling, it is only necessary to snap the annular groove 51 on the ejector bar 5 into the ejector bar seat 6 and the insert base. The chute 31,62 of 3 gets final product.

In this embodiment, a motor or a handle for driving the transmission rod 8 to rotate is also included.

In this embodiment, a T-shaped chute 32 is provided on the side of the insert base 3 close to the exhaust insert 2, and the exhaust insert 2 is engaged with the T-shaped chute 32. The extension direction of the T-shaped chute 32 is in line with the top The axial direction of the rod 5 is vertical. The exhaust insert 2 is clamped with the T-shaped chute 32. On the one hand, it can be quickly disassembled. It can be pulled out horizontally without pushing the insert base 3 out of the mold core 1 entirely.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model rather than limiting the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should It is understood that the technical solution of the utility model can be modified or equivalently replaced without departing from the essence and scope of the technical solution of the utility model.
