Abstract

The utility model discloses an injection mold with an automatic cutting gate and for the production of a PVC (Polyvinyl Chloride) pipe fitting. The injection mold comprises two cavities for molding the PVC pipe fitting, wherein each cavity comprises an upper mold and a lower mold, the two cavities are communicated with each other through a runner and a gate, and the gate is a submarine gate. According to the injection mold disclosed by the utility model, a direct gate is modified to the submarine gate, and therefore, the two molded PVC pipe fittings are automatically separated when ejected out to achieve the automatic cutting; simultaneously, as the position of the PVC pipe fitting corresponding to that of the gate does not need to be modified, the process is simplified, and the efficiency is high; the injection mold is applicable to the production of the PVC pipe fitting.

Description

Certainly cut the injection mould of cast gate for the production of the band of pvc pipe spare

Technical field

The utility model relates to a kind of injection mold, particularly relates to a kind of injection mould of cutting cast gate for the production of the band of pvc pipe spare certainly.

Background technology

Before the utility model proposes, mostly be a mould two cavity structures greatly for the production of the injection mould of pvc pipe spare, be communicated with by runner and cast gate between two die cavities, described cast gate generally adopts drop gate.Like this, also need after the described pvc pipe spare moulding by hand two pvc pipe spares to be cut off, and repair the position of corresponding described cast gate on the pvc pipe spare, complex process and efficient are low.

The utility model content

The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, provides a kind of technology simple and efficient is high for the production of the band of pvc pipe spare from the injection mould of cutting cast gate.

In order to realize above purpose, a kind of injection mould of cutting cast gate for the production of the band of pvc pipe spare certainly that the utility model provides, comprise two die cavities that are used for moulding pvc pipe spare that formed jointly by upper die and lower die, be communicated with by runner and cast gate between described two die cavities, described cast gate is sub marine gate.By drop gate is improved to sub marine gate, can separates automatically when two of moulding pvc pipe spares are ejected like this, thereby realize cutting certainly; Simultaneously, need not again the position of corresponding described cast gate on the pvc pipe spare to be repaired by hand, simplified technology and efficient height.

In such scheme, the quantity of described sub marine gate is at least 1.

The utility model can separate automatically when two of moulding pvc pipe spares are ejected like this, thereby realize cutting certainly by drop gate is improved to sub marine gate; Simultaneously, need not again the position of corresponding described cast gate on the pvc pipe spare to be repaired by hand, simplified technology and efficient height.

The utility model is compared with the prior art, and show that fully its superiority is: structure and manufacturing process are simple, and efficient is high.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation at the utility model die joint place.

Among the figure: patrix 1, counterdie 2, die cavity 3, runner 4, cast gate 5.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.

As shown in Figure 1: present embodiment provides a kind of injection mould of cutting cast gate for the production of the band of pvc pipe spare certainly, comprise two die cavities 3 that are used for moulding pvc pipe spare that formed jointly by patrix 1 and counterdie 2, be communicated with by runner 4 and cast gate 5 between described two die cavities 3, described cast gate 5 is sub marine gate.By drop gate is improved to sub marine gate, can separates automatically when two of moulding pvc pipe spares are ejected like this, thereby realize cutting certainly; Simultaneously, need not again the position of corresponding described cast gate 5 on the pvc pipe spare to be repaired by hand, simplified technology and efficient height.The quantity of described sub marine gate is at least 1.

The utility model can separate automatically when two of moulding pvc pipe spares are ejected like this, thereby realize cutting certainly by drop gate is improved to sub marine gate; Simultaneously, need not again the position of corresponding described cast gate 5 on the pvc pipe spare to be repaired by hand, simplified technology and efficient height.

Claims

One kind for the production of the band of pvc pipe spare from the injection mould of cutting cast gate, comprise two die cavities that are used for moulding pvc pipe spare that formed jointly by upper die and lower die, be communicated with by runner and cast gate between described two die cavities, it is characterized in that: described cast gate is sub marine gate.
2. the band for the production of pvc pipe spare as claimed in claim 1 is from the injection mould of cutting cast gate, and it is characterized in that: the quantity of described sub marine gate is at least 1.
