Abstract

The utility model discloses an improved structure for a hollow lattice-board mould head; the mould head comprises a mould body, a mould lip and a mould core, the mould core is arranged inside the mould body, the mould lip consists of a front mould lip and a back mould lip, the front mould lip is embedded inside the groove of the back mould lip, the mould body is fixed with the back mould lip through a fastening screw to divide the original integral mould lip into a front mould lip and a back mould lip, the volume of the front mould lip is designed smaller than usual, the front mould lip is arranged on the back mould lip with a fastening screw and the replacement of the mould core is made convenient and fast by dismantling front mould lip instead of the large-sized back mould lip when the mould core needs replacing. The original installing groove for the mould lip is removed from the mould body structurally and after the mould lip is dismantled, the flow passage inside the mould body is fully opened, therefore, the cleaning of the flow passage is convenient.

Description

The improvement structure of middle plate with grid open cavities die head

Technical field

The utility model relates to a kind of extrusion moulding equipment that is used for producing plate with grid open cavities, refers in particular to the structure of extrusion die.

Background technology

The extruding production line of plate with grid open cavities in the now used production through Vacuum shaping, combines different materials by extruder and co-extrusion distributor, goes out middle plate with grid open cavities by die head is compound.As shown in Figure 1, die head includes die body, die lip, fixes by holding screw between die body and the die lip, and core rod is arranged in the die body, and the structure of die lip is excessive in the process of assembly and disassembly, whole die lip dismounting could need be changed core rod; Die lip is mounted in the die body storage tank, and it is not abundant open exposure that die lip is disassembled the back runner, and is also inconvenient concerning the cleaning runner; When discharging is inhomogeneous, can only mould respectively to be distinguished temperature and the die lip micromatic setting is controlled by regulating, the amplitude of accommodation is limited.

The utility model content

At the defective that exists in the technique scheme, the purpose of this utility model is to provide a kind of improvement structure of middle plate with grid open cavities die head, is convenient to dismantle die lip, can clear up runner after die lip is disassembled more easily and change core rod.

Reach by following technical solution for achieving the above object:

The improvement structure of middle plate with grid open cavities die head, die head is made up of die body, die lip and core rod, and core rod is arranged in the die body, it is characterized in that: die lip is made up of preceding die lip and back die lip two parts, preceding die lip embeds in the groove that is installed in the back die lip, and die body is fixed by holding screw with the back die lip.

Described back die lip is provided with the throttle bar adjustment structure, described throttle bar adjustment structure is made up of throttle bar and adjusting device, adjusting device includes and regulates bolt, regulates briquetting and adjusting nut, and adjusting bolt lower end penetrates and regulates briquetting, the back die lip is connected with throttle bar.

Described die body is provided with three row's heating rods.

The utility model adopts multimode lip combined structure design, original whole die lip is divided into preceding die lip and back die lip two parts, preceding die lip volume ratio designed little in the past, be installed on the die lip of back by holding screw, when needing to change core rod, die lip just can be changed core rod before only needing dismounting, need not dismantle bulky back die lip, and it is very convenient to change core rod; Die body has been cancelled original whole die lip from structure groove has been installed, after disassembling die lip, the runner in the die body is unlimited fully, is convenient to clear up runner, when installing die lip direct the contact by holding screw with the die body interface in back fixed, fitting operation is simple and convenient; On the die lip of back, increased the throttle bar adjustment structure, can regulate local flow, improved adaptability the property of raw material different situations; The three row's heating rods that are provided with on the die body can make die head reach and produce needed temperature, can solve the uneven phenomenon of discharging.

Description of drawings

Fig. 1 is the utility model prior art constructions schematic diagram;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 2, the improvement structure of plate with grid open cavities die head during the utility model provides, die head is by die body 1, die lip 2 and core rod 3 are formed, core rod 3 is arranged in the die body 1, die lip 2 is made up of preceding die lip 21 and back die lip 22 two parts, preceding die lip 21 embeds in the groove 221 that is installed in back die lip 22, die body 1 is fixing by holding screw 4 with back die lip 22, multimode lip combined structure design, original whole die lip is divided into preceding die lip 21 and back die lip 22 two parts, preceding die lip 1 volume ratio designed little in the past, be installed on the die lip 22 of back by holding screw 4, when need changing core rod 3, only need dismounting before die lip 21 just can change core rod 3, need not dismantle bulky back die lip 22, such structure makes that replacing core rod 3 is very convenient.

As shown in Figure 2, back die lip 22 is provided with throttle bar adjustment structure 5, described throttle bar adjustment structure 5 is made up of throttle bar 6 and adjusting device 7, adjusting device 7 includes and regulates bolt 71, regulates briquetting 72 and adjusting nut 73, adjusting bolt 71 lower ends penetrate and regulate briquetting 72, back die lip 22 is connected with throttle bar 6, it is local mobile about in the of 6 to regulate throttle bar by adjusting device 7, thereby the local flow in the adjustable throttle road improves the adaptability of die head to the property of raw material different situations.The three row's heating rods that are provided with on the die body can make die head reach and produce needed temperature, can solve the uneven phenomenon of discharging.

Claims
