Description

Injection mold of plastic cell phone case production usefulness

Technical Field

The utility model relates to an injection mold technical field specifically is an injection mold of plastic cell phone case production usefulness.

Background

An injection mold is a tool for producing plastic products; and is also a tool for giving the plastic product complete structure and accurate dimension. Injection molding is a process used to mass produce parts of some complex shapes. Specifically, the plastic melted by heating is injected into a mold cavity from an injection molding machine at high pressure, and a formed product is obtained after cooling and solidification.

At present, in the production process of plastic mobile phone shells, after plastic is injected into an injection mold, the plastic in the injection mold needs to be cooled for a certain time, so that products are molded. But the mould carries out natural cooling among the prior art, not only the waste time, the efficiency of great reduction product production moreover to after the product shaping, the product can be hugged closely on the inner wall of die cavity, and when the workman used professional instrument to come out the finished product clamp, the condition that the plastic product damaged appears easily.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an injection mold of plastic cell phone case production usefulness to solve among the prior art mostly carry out natural cooling to the mould, not only the waste time, the efficiency of great reduction product production moreover, and after the product shaping, the product can be hugged closely on the inner wall of die cavity, when the workman uses the instrument of specialty to press from both sides the finished product out, the problem of the condition of plastic product damage appears easily.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an injection mold of plastic cell phone case production usefulness, includes the bed die, the heating panel has been laid in the die cavity of bed die, be equipped with the water cavity in the heating panel, conduit is all installed to the water inlet and the delivery port in water cavity, conduit's one end runs through the bed die, and conduit wears out the one end and installs water pipe head.

Preferably, a cavity and a positioning hole are arranged in the lower die, and a hook rod is sleeved in the positioning hole.

Preferably, all be equipped with the circular port on bed die and the heating panel, the one end of gib block is established to the circular port endotheca.

Preferably, a sliding groove is formed in the hook rod.

Preferably, the sliding groove is internally sleeved with a lifting rod, and the upper end of the lifting rod is provided with an upper die.

Compared with the prior art, the beneficial effects of the utility model are that: the upper die drives the lifting rod and the hook rod to be linked, so that one end of the hook rod is moved out of the circular hole, a product in the lower die can be ejected out, and the product is convenient to demould; through water pipe to the water cavity water injection, make water carry out the heat exchange through heating panel and product, can accelerate product shaping in the mould, not only can reduce the waste of time, can improve the production efficiency of product moreover.

Drawings

FIG. 1 is a front cross-sectional view of the overall structure of the present invention;

fig. 2 is a top view of the lower mold of the present invention.

In the figure: the die comprises a lower die 1, a heat dissipation plate 2, a water cavity 3, a water pipe 4, a water pipe joint 5, a cavity 6, a positioning hole 7, a hook rod 8, a circular hole 9, a sliding groove 10, a lifting rod 11 and an upper die 12.

Detailed Description

Referring to fig. 1 and fig. 2, the present invention provides a technical solution: the utility model provides an injection mold of plastic cell phone case production usefulness, including bed die 1, heating panel 2 has been laid in the die cavity of bed die 1, 2 sealing weld of heating panel are in bed die 1, heating panel 2 is made by the copper product material, be equipped with water cavity 3 in the heating panel 2, conduit 4 is all installed to the water inlet and the delivery port of water cavity 3, conduit 4 is through sealed threaded connection at water inlet and delivery port, conduit 4's one end runs through bed die 1, and conduit 4 wears out one end and installs water pipe joint 5, be equipped with the pore on the bed die 1, conduit 4 pegs graft in the pore, 5 sealing weld of screwed joint is on conduit 4.

Referring to fig. 1 and 2, a cavity 6 and a positioning hole 7 are formed in a lower die 1, a hook rod 8 is sleeved in the positioning hole 7, circular holes 9 are formed in the lower die 1 and a heat dissipation plate 2, one end of the hook rod 8 is sleeved in the circular hole 9, a sealing ring is arranged on the surface of the hook rod 8, the sealing effect between the hook rod 8 and the circular hole 9 is ensured, a sliding groove 10 is formed in the hook rod 8, a lifting rod 11 is sleeved in the sliding groove 10, an upper die 12 is installed at the upper end of the lifting rod 11, the lifting rod 11 is welded on the upper die 12, and when the lower die 1 and the upper die 12 are closed, the hook rod 8 moves into the cavity 6 and the circular hole 9, so that one end of the hook rod 8 is flush with.
