Problems solved by technology
[0002] like figure 1 As shown, it is a part on the vacuum cleaner, which includes a shell A and two elbows B. In the prior art, it is usually necessary to make several complicated plastic parts and then combine them into one part, for example, make the shell A and the two elbows B respectively. After the pipe B is bent, the pipe B and the shell A are combined to form a part of the vacuum cleaner. This production method has many processes, and it will not be able to effectively shorten the production cycle and reduce the production cost of the product; and because different parts are located in different On the plane, for example, the elbow B and the shell A are respectively located on the intersecting planes, and the position of the elbow B hinders the opening direction of the shell A. If the male and female molds are used to close the mold, the elbow B and the shell A cannot be formed at the same time. It also limits mold production, product shape and function design

Embodiment Construction
[0014] refer to Figure 2 to Figure 4 , the present invention is an injection molding composite mold for vacuum cleaner shell parts, comprising a front mold 1, a rear mold 2 and a curved row part, the curved row part is located below the front side of the rear mold 2 and obliquely intersects with the rear mold 2 Setting, that is, the plane where the curved row position part is located intersects the plane where the rear mold 2 is located. The front mold 1 and the rear mold 2 are provided with corresponding slots, and the front mold 1 and the rear mold 2 are opened and closed up and down to form a molding cavity (not labeled). Such as Figure 5 to Figure 7 As shown, the curved position part includes a curved position seat 3, a driving curved position part 30, a pair of curved position pull rods 31 driven by the injection molding machine installed on the curved position seat 3, fixed A pair of curved row position fixing rods 32 , a curved row position rotating block 33 and a f...

The invention relates to a compound die. The compound die comprises a front mould and a back mould which are provided with slot positions; the front mould and the back mould surround a shaping mould cavity; the compound die also comprises a curved slide part which comprises a curved slide seat, a curved slide pull rod, a curved slide rotating block and a fixed curved slide core; the curved slide pull rod can be movably arranged on the curved slide seat along the self axes; the axes of the curved slide pull rod is crossed with the molding mould cavity formed by the front mould and the back mould; furthermore, the front end of the curved slide pull rod extends into the back mould; one end of the curved slide rotating block is fixedly arranged at the front end of the curved slide pull rod and the other end is contacted with the end part of the fixed curved slide core; besides, the curved slide rotating block can rotate along a pivot; the curved slide rotating block and the fixed curved slide core are arranged in the back mould. The compound die of the invention can shape the parts with pull direction being different from a main die at one time, thus reducing the manufacture working procedures.
Description
technical field [0001] The invention relates to an injection mould, in particular to a mould, which is compounded with a curved row position, an oblique row position and an inclined top, which can be used to form vacuum cleaner parts by one-time injection molding. Background technique [0002] Such as figure 1 As shown, it is a part on the vacuum cleaner, which includes a shell A and two elbows B. In the prior art, it is usually necessary to make several complicated plastic parts and then combine them into one part, for example, make the shell A and the two elbows B respectively. After the pipe B is bent, the pipe B and the shell A are combined to form a part of the vacuum cleaner. This production method has many processes, and it will not be able to effectively shorten the production cycle and reduce the production cost of the product; and because different parts are located in different On the plane, for example, the elbow B and the shell A are respectively located on the...
