Abstract
The utility model relates to a kind of mould structure for making PVC bend pipe, comprise upper and lower mould Renhe executing agency, described upper and lower die is respectively carved with the groove for fixing PVC pipe, and described executing agency and upper cores are in transmission connection, and promotes upper cores matched moulds in lower die.Compared with prior art, it is wide that the utility model has the scope of application, is applicable to the preparation method of all bend pipe products; Administration measure, makes simple and produces in batches, improving make efficiency.
Description
Technical field
The present invention relates to a kind of mould structure, especially relating to a kind of mould structure for making PVC bend pipe.
Background technology
PVC bend pipe mould, refers to the pipeline after to extrusion molding, then carries out bending process by mould, is also a kind of tool of production producing out the product with definite shape and performance requirement by batch simultaneously.
At present for PVC bend pipe, market does not have specific equipment process, the processing mode of each company is different, and production method substantially has following several:
Clod wash: at normal temperatures because intensity is stretched in certain drawing of plastics itself, carry out bending process in tube wall insertion work to pipe, main applicable wall ratio is thinner, and angle of bend is little, the product that instructions for use is not high.
Hot bending: bend inserting tube wall after instrument heating, after waiting pipe cooling and shaping, then extracted out by instrument, the method easily causes inwall to damage, and fabrication cycle is partially long, increases cost of labor.
Summary of the invention
Object of the present invention be exactly in order to overcome above-mentioned prior art exist defect and a kind of mould structure for making PVC bend pipe is provided.
Object of the present invention can be achieved through the following technical solutions:
A kind of mould structure for making PVC bend pipe, it is characterized in that, described mould structure comprises upper and lower mould Renhe executing agency, and described upper and lower die is respectively carved with the groove for fixing PVC pipe, described executing agency and upper cores are in transmission connection, and promote upper cores matched moulds in lower die.
Described lower die upper surface is the identical rectangle of area with upper cores lower surface, and four corners on described lower die upper surface are respectively arranged with 4 root posts, and described column is from described upper cores lower surface through upper cores, and described upper cores slides up and down along column.
The die that described die up and down all adopts aluminium to be made.
Also cooling water channel is comprised in described die up and down.
Described cooling water channel is specially the described groove inner wall for fixing PVC pipe and is provided with water spray osculum.
Described executing agency is cylinder or oil cylinder.
Compared with prior art, the present invention has the following advantages:
1) scope of application is wide, is applicable to the preparation method of all bend pipe products.
2) administration measure, makes simple, batch production, improves make efficiency.
Accompanying drawing explanation
Fig. 1 is mould structure schematic diagram;
Reference numeral: 1, upper cores, 2, lower die, 3, cylinder, 4, product.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, for making a mould structure for PVC bend pipe, mould structure comprises upper cores 1, lower die 2 and cylinder 3, and upper and lower die is respectively carved with the groove for fixing PVC pipe, described executing agency 3 is in transmission connection with upper cores 1, and promotes upper cores 1 matched moulds in lower die 2.Lower die 2 upper surface is the identical rectangle of area with upper cores 1 lower surface, and four corners on lower die 2 upper surface are respectively arranged with 4 root posts, and column is from described upper cores lower surface through upper cores 1, and described upper cores 1 slides up and down along column.The die that upper and lower die all can adopt aluminium to be made, contributes to inner heat conduction.Also cooling water channel can be set in upper and lower die, namely water spray osculum be set at the groove inner wall for fixing PVC pipe.
Utility model works process is as follows:
(1) by needing bending PVC pipeline to be cut into certain length, bending position is heated;
(2) PVC pipeline after heating is embedded in the groove of lower die;
(3) by upper cores matched moulds in lower die;
(4) after cooling PVC pipeline is taken out.
Embodiment 2
During use, first pipeline is cut into certain length, heats bending position, the product after heating is put into lower die 2, and open jettron, product 4 in bed die 2, takes out by cylinder 3 action by upper cores 1 matched moulds after cooling.
Claims (6)
1. one kind for making the mould structure of PVC bend pipe, it is characterized in that, described mould structure comprises upper and lower mould Renhe executing agency, and described upper and lower die is respectively carved with the groove for fixing PVC pipe, described executing agency and upper cores are in transmission connection, and promote upper cores matched moulds in lower die.
2. a kind of mould structure for making PVC bend pipe according to claim 1, it is characterized in that, described lower die upper surface is the identical rectangle of area with upper cores lower surface, four corners on described lower die upper surface are respectively arranged with 4 root posts, described column is from described upper cores lower surface through upper cores, and described upper cores slides up and down along column.
3. a kind of mould structure for making PVC bend pipe according to claim 2, is characterized in that, the die that described die up and down all adopts aluminium to be made.
4. a kind of mould structure for making PVC bend pipe according to claim 3, is characterized in that, also comprises cooling water channel in described die up and down.
5. a kind of mould structure for making PVC bend pipe according to claim 4, is characterized in that, described cooling water channel is specially the described groove inner wall for fixing PVC pipe and is provided with water spray osculum.
6., according to a kind of mould structure for making PVC bend pipe described arbitrarily in claim 1-5, it is characterized in that, described executing agency is cylinder or oil cylinder.
