Description

Inspection well mold for easy demolding

technical field

The invention relates to the field of moulds, in particular to an inspection well mould which is convenient for demoulding.

Background technique

The inspection well is an auxiliary structure on the pipeline system. Its main function is to regularly inspect and clear the pipeline system, and also to dredge the water flow. Inspection wells are usually located at conduit intersections, turns, changes in conduit size or slope, water drops, etc., and on straight conduits separated by a certain distance. At present, in order to improve production efficiency and reduce production costs, most inspection wells are made of plastic.

The current inspection well usually includes a well body, the top of the well body is a main pipe, and the side is a branch pipe. For example, the existing patent with the publication number of CN203960992U discloses an inspection well well seat, which includes a well seat, and the upper end of the well seat is provided with a well seat. There is a wellbore socket, at least one drain pipe socket is arranged on the side wall of the well base, annular reinforcing ribs are arranged on the outer wall of the wellbore socket and the drain pipe socket, and there is a 360-degree socket between the wellbore socket and the well base. There is a 360-degree socket in the drain pipe socket, and the 360-degree socket is an annular arc structure; combined with the drawings in the manual, it can be clearly seen that there is a gap between the drain pipe socket and the wellbore socket.

For the above-mentioned inspection well, since there is a gap between the drain pipe socket and the wellbore socket, it is necessary to separate the drain pipe socket and the wellbore socket module set in the gap when demoulding. The socket and the wellbore socket are perpendicular to each other, and the structure of this position is relatively fragile, especially when the injection has just been completed, the material is often completely cooled when demoulding is completed, so it is easy to cause damage to the product when there is no demoulding. Redesign.

SUMMARY OF THE INVENTION

Aiming at the deficiencies in the prior art, the present invention provides an inspection well mold that is easy to demould, and the technical purpose of the solution is how to demould without damaging the product.

The above technical purpose of the present invention is achieved through the following technical solutions: an inspection well mold for easy demoulding, comprising an upper mold and a lower mold that can be closed or separated from each other, the upper mold is arranged on one side relative to the lower mold There are four upper side sliding modules, and the side of the lower mold relative to the upper mold is provided with four lower side sliding modules, and the positions of the upper side sliding modules and the lower side sliding modules correspond to each other, and the upper side sliding modules can be The lower side sliding module can perform an outwardly expanding tilting motion relative to the upper mold, and the lower side sliding module is provided with a first mold cavity and a second mold cavity. When the lower side sliding modules are closed, the first mold cavity and the second mold cavity of all the lower side sliding modules are respectively used to form the main receiving pipe and the lower half of the branch pipe of the inspection well, and the upper side sliding module is provided with a third mold cavity , when the four upper sliding modules are closed, the third cavity is used to form the upper half of the branch pipe of the inspection well.

Through the above technical solution, the structure of the inspection well is divided into upper and lower parts, and the two parts are respectively injection-molded in the upper side sliding module and the lower side sliding module, and the upper side sliding module and the lower side sliding module have four structures. When demoulding, it can expand outwards by tilting, so that the mold cavity and the injection-molded product are slowly separated, improve the stability during the demoulding process, and reduce the damage to the product caused by the demoulding. In the injection molding structure of the inspection well, the main receiving pipe and the branch pipe that undertake the main separation force are set at the bottom, that is, the lower side sliding module, so that when the separation is performed, the force of the separation is basically the force of the ejection, rather than the pulling force. In this way, it will not hurt the product. At the same time, with the number of four lower sliding modules, the lower sliding modules can expand outwards in all directions during demolding, the demoulding force will not be concentrated, and the surface of the product will not be damaged basically. Combined with four upper side-slip modules, the lower part of the product is less likely to be stuck by the upper part when demoulding, and the upper part of the product can be separated quickly and limitedly without affecting it.

The present invention is further provided that: the upper side sliding module and the lower side sliding module are both provided with a fourth mold cavity for forming the inspection well body, the upper mold is provided with an upper core, and the lower mold is provided with a fourth mold cavity. There is a lower core, the lower mold is also provided with a side extraction block for side extraction, the side extraction block is provided with a side extraction core, the upper core and the lower core can be inserted into the second cavity and In the fourth mold cavity, the side-pulling core can be inserted into the second mold cavity and the third film cavity. When the mold is closed, the upper mold core, the lower mold core, the first mold cavity and the fourth mold cavity are The gap between them forms a space for forming the inspection well body and the main bearing pipe, and the gap between the side-drawn core, the second mold cavity and the third mold cavity forms a space for forming the inspection well branch pipe.

Through the above technical solution, the structure of the side-drawing block and the side-drawing core can improve the demoulding efficiency of the product to a relatively fast degree, and jointly construct the internal structure of the inspection well.

The present invention is further provided that: the side of the side-pulling core away from the side-pulling block is provided with an elastic block that can move downwards obliquely; The side-drawing core is provided with a movable cavity for accommodating the elastic block, and the movable cavity is provided with an elastic member for driving the displacement of the elastic block and a side-drawing inclined guide block for guiding the sliding of the elastic block.

Through the above technical solution, the elastic block can be used to form the arc surface on the inner side of the inspection well. However, because the elastic block is used to construct the inner surface, if it is pulled straight away with the side-pulling core, it will hook the product and make it difficult to operate normally. Therefore, structures such as side-pulling guide blocks are installed in the side-pulling core. When the mold is opened, due to the displacement of the side-pulling core, there will be space in front of the side-pulling core, and the elastic piece can drive the elastic block. It is pushed forward along the side-drawing inclined guide block, so that the elastic block can move to the inner side and downward, so that it can be separated from the product, and finally can be separated together with the side-drawing core. When the mold is closed, due to the inward movement of the side-pulling core, the elastic block will also return to its original position due to the conflict of the internal space.

The present invention further provides that: the upper mold is provided with an upper inclined guide block for the upper side sliding module to slide, and the lower mold is provided with a lower inclined guide block for the lower side sliding module to slide.

Through the above technical solution, the structure of the upper inclined guide block and the lower inclined guide block can effectively stabilize the sliding trajectory of the upper side sliding module and the lower side sliding module, and avoid the situation such as shaking during the sliding process.

In the present invention, the cross sections of the upper inclined guide block and the lower inclined guide block are both T-shaped.

Through the above technical solutions, the upper inclined guide block and the lower inclined guide block of the T-shaped structure are stably installed, and a sufficient guiding force can be improved.

The present invention further provides that: the elastic member is a spring.

Through the above technical solutions, the spring can provide long-term stable elasticity and reliable performance.

The present invention further provides that: the upper side sliding module, the lower side sliding module and the side pulling block are all driven by an oil cylinder.

Through the above technical solutions, the driving force of the oil cylinder is strong and the efficiency is high, and the overall operation of the mold is stable and efficient.

The present invention further provides that: the side-pulling core and the side-pulling block are detachably connected.

Through the above technical solution, since it is a detachable connection, the side-pulling cores of some side-pulling blocks can be replaced according to the number of ordered inspection well branch pipes when injecting inspection wells, so that one mold can be used for multiple purposes.

To sum up, the beneficial effects of the present invention compared with the prior art are:

1. The main bearing interface of the inspection well and the upper half of the branch pipe are designed in the lower side sliding module, so that the ejection force is used for demoulding during demoulding, which changes the original pulling force and protects the product structure;

2. By designing four one-to-one corresponding upper side sliding modules and lower side sliding modules, the demoulding force is evenly distributed when the product is demolded, avoiding local stress and avoiding mold sticking.

3. Through the structural design of the elastic block, the injection molded product can be directly molded to the inner chamfer surface without secondary processing.
